There's 3 things that really stand out for me that I would say made a massive difference to my life:
Cordless screw driver. Bought the day after building a flat pack bed with a crappy screw.driver that just shredded my hand. Thought it was frivolous at the time, but I've used it so much since. It's light, small enough to fit in my pocket and good for 90% of DIY tasks.
Tassimo coffee machine. Bought it 9 years ago, use it every day. Nice quick easy coffee. What's not to like.
My first DSLR camera. It was a Nikon D50 back in 2005/6 and it sparked my interest in photography to this day. It gave me a hobby I can take lots of places and do it alone or with others.
I never loved the D50 camera itself, but I did get some really nice shots with it
I bought a 97 Ford Taurus off a friend for $800 back in 2008. Her dad thought it was on its last legs at 155k miles so he wanted to sell it. I drove it for four years. It was running fine until someone blasted it out in front of my girlfriend’s house and drove off. At the time it had 206k miles. 50k miles for $800 was certainly one of my best purchases.
Back in 2017 while stationed in AZ I adopted a dog who was the cutest little Blue Heeler, for $5 we have been inseparable since and she is the single greatest thing that's happened to me.
Last year in April my Powerstrokes transmission failed and on a whim I bought a 98' 4 runner with 245k miles. We have now built the hell out of that little rig and have put 15k miles on it in 11 months
100 pairs of socks on Amazon. This sounds nuts but, I got 100 pairs of black socks 2 years ago for $60 because I was tired of my socks always missing. I still have 50 socks I haven't touched.
A plot of land in a place I like. Nothing fancy or huge, just a place to be by myself and enjoy a nice bonfire away from people.
Headphones. The old clunky ones that cover your whole ears. I love them! They feel like a hug and I use them all the time while listening to spooky stories. Bought them in a sale about four years ago.
A hello kitty backpack. Bought it as a birthday gift for a friend's daughter, we had a fallout and I kept it. One day I needed a clean backpack and this was on hand so I grabbed it in a whim and have been using it ever since.
I have a pair of Columbia, silver ridge and tetons laying around but this fluffy cute backpack makes me so happy and has the perfect size.
Smart vacuum cleaner - you pay a reasonable amount once and don't have to vacuum anymore
Vaporiser - switched to vaping weed instead of smoking joints which is not only nicer in many ways but also allowed me to quit smoking cigarettes
PlayStation - after sitting 8h by the desk moving a mouse for work, I didn't want to sit in the same position another few hours playing games. With PS I can comfortably sit in my armchair and play on a big tv scrreen using a controller
Ergonomic mattress - healed my hurting back. This should be on the top of this list.
My recliner that I bought with one of the first Covid check. I have horrendous back issues (3 major surgeries and constant pain) and having another resting/sleep area has been a lifesaver many times. Currently pregnant and it’s one of the only places I can sleep.
This set of 2 grabbers from Amazon. They weren’t super expensive but nicer than other grabbers commonly bought by others. They have been used daily by me, my toddler plays with them, they get dropped, etc. and they perform so well. I can pick up the tiniest item off the floor, a piece of paper, etc. with no issues. Had them 3 years. I keep one on each floor of the house and they save my back so much. It’s one of the only ways I can do chores and keep the floor clean from a toddler.
Silly, but this last year I really appreciated having a laminator at home. It’s nothing fancy- just a simple one from Scotch from the store. I’ve laminated different rules for games (card games where we wrote out the rules) and my son absolutely LOVES when I draw him characters and items from his favorite shows, laminate them, and then he plays with them for months. It’s saved us a ton of money buying toys he doesn’t need, stores easily, and he loves it. It also gets out some of the creative side that I kind of lost the last few years.
My horse, Lola. She’s an amazing 9yo grey quarter horse mare. “Retired” barrel racer, she’s the perfect trail/ranch horse. She’s got the best quirky and silly demeanor, she loves to hang out, and she’s playful, but never gets crazy under saddle.
My guitar. 2012 PRS 513. I absolutely love that guitar, and it got me back into playing after almost 20 years off. It’s my “do everything” guitar, and the difference in sounds between pickup combinations makes it incredibly versatile.
A good mattress. I spend a solid 1/3 of my life sleeping (or trying to) and a great mattress helps so much.
Steam Deck - since having kids I was really struggling to play games at all. I had gotten to where I was only playing phone games and switch games, but the Steam Deck has really enabled me to start enjoying my steam library again. If it broke I would buy another one instantly.
Bone-conductive headphones - I wear these all day. I listen to audiobooks, take calls, have them read out notifications, etc. It's also great to know that if I open a random meme video on my phone, I don't have to worry about the sounds of the video being inappropriate for my surroundings. They're so much more comfortable than traditional headphones.
My house - I got an insanely good deal on my house, less than what many people pay for cars. It's not the fanciest house, and it needed some fixing up when we bought it, but it's enabled me and my family to live with extremely low bills which has made my life very low stress. Houses are generally cheap where I live, but I lucked out and got the best house deal I've seen, and it's made everything so much easier.
Boring answrs but.. A computer. It's the 2nd most expensive thing I own and it's provided me thousands and thousands of hours of entertainment and use as tool.
A car. The most expensive thing I've brought and very useful. I've been able do a lot more with my time and get into many new hobbies.
Power rack. 3rd most expensive. Having a power rack in my garage allows me to safely lift heavy by myself which is awesome.
Bonus cheap thing. Screw driver set. Allowed me to fix many things around my house and easily saved me 10x the cost.
1. First vape (a cigarette-shaped item from the corner store, cherry flavor). I had been smoking with suicidal enthusiasm for 18 years. I was out of breath, coughing, stinking, and (at $7 a pack) broke. A decade later, I still vape, but I can breathe now.
2. First not-fully-depreciated used car (3-year-old 2012 Focus SEL hatch with 30K mi). Apart from warranty transmission work, the car's been stable, and pretty. The real change was introducing me to finance and lending. I grew up poor with a debt addicted dad. At 32, I had never had a credit card. I've still never given the bastards a dime, but I've pulled in thousands in rewards and have an outstanding credit score.
3. Passport / first international airline ticket. I mean, yeah. I hadn't had any desire to leave my state, let alone see the world. At 20, I grudgingly flew to Europe to visit my girlfriend who was studying abroad. We didn't last, but the travel bug did.
Honorable mention, only because it isn't technically a purchase would be my first union payment. Best deal ever.
Edit: how do you add line breaks? It worked, magically, when I made the list heading bold, but that was hella annoying.
Steam Deck, handheld gaming computer, barely use PS5 anymore, this one is so quick and convenient to just pause and resume games and take gaming everywhere and the SteamOS Linux is awesome. I use the desktop mode with full KDE Plasma desktop as my portable computer a lot when on the go. Also with the dock station I can use it as a gaming console when going on holidays.
And the flat I live in. Good thing as I bought it quite a few years ago since the home prices are just criminal and highly unjust now. This stuff does not belong on markets to be sold for profits or some criminal short-time renting crap like AirBnB
My house. Bought it in 2019 right before the market went completely wacky. More of a lucky timing situation, but I'm extremely thankful to not be renting anymore.
A really high quality mattress. You're supposed to spend about a third of your life sleeping, and the quality of that sleep has a huge impact on your physical and mental health.
A really good set of kitchen knives. I hate having to cook at other people's places because of it, so many people have cheap, dull knives that do not do the trick. At my in-laws house I basically have to hammer tomatoes in half with their knives. FYI, you're more likely to cut yourself with a dull knife rather than a sharp one.
A bicycle. I have saved so much money over the years on cars, gym memberships, and therapy. I ride every day for most destinations, and I think that getting regular exercise has saved me from the aches and pains of middle age. I still haven't experienced the horrors that await (if Lemmings are to be believed) of turning 30. And it makes getting places enjoyable.
My first computer, an Amiga 500. I learned so much about software, IT, and human nature by persevering with an oddball (for the U.S.) computer.
A trailer sailboat. Aside from the hours spent on the water, along with it comes a whole raft (hah!) of hobbies/side pursuits: Marlinspike work, sewing, electrical wiring, navigation, weather forecasting, fiberglass repair, radio communications, and such. Strangely enough, it also served me well through years of low income, by providing a lot of hours of enjoyment for the money.
1987 ford “exp”: bought it for $500, drove a few years, got hit and insurance paid out $500 and let me keep it, drove it with damage for another few months, sold it for $500.
Breville oven. Found it at a consignment shop for $17, looked to have been used once.
House: bought in 2017 in a rural area to get away from the city occasionally. Moved there permanently during Covid.
E-reader. I'm not reading 4-5 books a month as I did before but it reignited my desire to read after losing it in college (plus: it's way cheaper).
Chemex. I was used to burnt gas station coffee and it gave me a new hobby.
First DSLR as well. Helped me think about composition more in my paintings, as well as contrast. I haven't touched a camera in years though. Little opportunity or desire.
Like OP, my camera, phones don't cut it and the pictures I've been able to get of my kid with it have made it invaluable. I got the Canon Powershot MKIII and it's gotten some professional quality shots of him and captured a lot of precious moments.
My electric kettle, I drink a lot of tea and it's so damn useful. I got one with an all metal interior and no visible heating element, it has a bad pour but I still would have a noticeable dip in my daily quality of life without it.
This one is random but a three foot tall solid wood Balinese dragon statue. I got it at an import shop that was closing, it had some damage and so had been marked down and marked down again. I paid less than 10% of the original price of an intact one. We didn't have a car so my boyfriend at the time and I had to take it with us on the subway. It's like 75lbs. On our ~mile walk back to our apartment someone asked directions to a local Asian art exhibition and we had to tell them we didn't know where it was while holding this thing between us. It's beautiful despite the damage and it makes me happy every time I see it. Plus, whenever someone comments on it I have a fun story to share.
1: My motorbike - hands down my best purchase. That has single handedly done more for my mental health than the last 9 years of various anti depressants.
2: My PC - the same as others. It's just nice to be able to have the option to do just about everything.
3: A car - I didn't really buy this. My mum gave it to me as a first car. It's not the flashiest. It's just the most basic type. But I love it. I spent 23 years just putting off getting my licence until I just decided to get it just to get it out of the way. And I have missed put on so much by it. The sense of freedom, not having to rely on getting lifts, or getting public transport. (Not opposes to public transport. It's just that where I live, it's a pain for commuting)
DDR dance deck. I have used it regularly to this day and it's my primary exercise. I have replaced the panels as they broke with new hand cut pieces and the electronics have seen 4 or so revisions of diy before settling on a Arduino clone based USB input with 3d printed shell.
Nothing else really. It all seems okay at first but breaks down and diy repairs are rarely an option these days. Sometimes I can 3d print parts but I can't just recommend that method to anyone.
Mountain bike - on my second bike now, my favorite hobby and form of exercise, excuse to get in nature with my dog, explored a lot of my state because of it.
Kobo e-reader. The night light is amazing, I used to use a neck light for night reading to not wake my wife but this is way better. Easier to travel. The dyslexic font helps my dyslexic ass like 10% too which makes a huge difference in me reading more.
My first raspberry pi in Jr high led to a career in software. Still love pis, and have even more toys now
My Panasonic Lumix GX80, it is the camera that made me take a deeper interest and develop my skills in photography. I had a Canon EOS 400D as my first decent camera but due to work my interest fizzled out for a few years. Then at another job I got my GX80, and started learning for real, last spring I upgraded to a Lumix S5, and I am considering complementing my camera setup with a Sony A7 IV for it's excellent AF.
My Philips Hue system has been absofuckinglutely amazing, I live alone and being able to turn my lights on before I open my apartment door during winter after work really makes a huge impact on my mwntal health, getting to open my front door into a cozy apartment instead of a black hole is fantastic
Supersonic cleaner - it can clean anything, it is simply amazing.
Lumix GX80, a M43 camera - it has everything right, the grip, the compactness, easy menu, the mechanical switches..etc on top of that, inexpensive. It allows me to carry it as if it is an action camera.
My bike. I use it daily to get to work, to the super market, visiting friends. It keeps me healthy I do not need a car and I can drive wherever I want all the time. It cost me 500€.
My Bodom french press. I use it daily to quickly make 2-4 cups of coffee, it tastes fantastic, provides coffee and is high quality. 35€.
My Amplifier and Wharfedale speakers. I bought them 2 years ago for 500 €. All my life I had cheap active computer speakers or bluetooth boxes. Everytime I tune them up, it get's a little warmer in my tummy.
All 3 things are far away from high end, people spend the multiple on what I spent. Still they all make me super happy and I will watch and keep them until one of us dies.
My Garmin Fenix watch, it was during the first month of wearing it that I realized my life and fitness can be like a video game and I get badges and points for doing things. It drives me to move and even after 4 years, it still is making me motivated.
A nice wallet, I looked for a long time and ended up with a Trayvax wallet. I just love the damn thing, it'll last me forever and it's unique and functional. Each time I pull it out of my pocket, I appreciate it's look and feel and form.
My osprey back pack. I've carried it to and from work, on boats, kayaks, walking, for camping and to my friends houses. It is just so functional and comfortable in a way that a less expensive one isn't. It's made to be comfortable AND hold things.
Quality electric toothbrush. I can't get my teeth feeling clean without one anymore.
A rice cooker. Doesn't need to be fancy, but it lowers the barrier to cooking substantially given how many dishes use rice.
3, A phone with a camera that's at least mid-range, as it's the camera you'll have on you most. I used to always use phones from cheap brands like Umidigi and although some of them did perform quite well others left me with gaps of my life where none of the photos I took have any detail.
Cordless screw driver. Bought the day after building a flat pack bed with a crappy screw.driver that just shredded my hand. Thought it was frivolous at the time, but I've used it so much since. It's light, small enough to fit in my pocket and good for 90% of DIY tasks.
Got a gun from sako the other day it's cute, it's small, fits right in my pocket (yeeeeeah right in my pocket)
Real answers tho:
Air pump for car tires. I have notoriously bad luck with flats, leaks, etc. This thing has saved me more than a few times.
KVM switch. I work from home, this lets me have my work computer and my personal computer connected to the same equipment, and I can toggle between them with either a physical switch or a keyboard hotkey
Bit of a curve ball, but therapy. Life's tough, gotta have some outlets and advice sometimes.
8 Sleep Bed—it’s liquid cooled and heated based on your sleep stage. I know it’s expensive, but the sleep it’s given me has been unrivaled by anything else I’ve ever used to regulate my sleep. I work shifts so good sleep is priceless. You spend a third of your life asleep, so it’s worth an investment.
Hue lights for my entire home—privacy issues aside, it’s a game changing investment. We replaced the recessed lighting with recessed hue lighting fixtures as well. It’s insane how having multiple lighting settings and colors for times of the day/moods can change your entire mindset.
Home gym—if I were pressed for one component it would be the power cage and Olympic bar, but investing in a fully functional home gym has given me much more in return than what I’ve put into it (whether that be physical work building equipment or money).
My Nvidia Shield TV Pro 2019 and a Synology NAS (sorry they go together), no more dealing with ugly Smart TV or limited game consoles to stream, and it is also very easy to sail the seas with it!
Android phone in 2020 (Poco F2 Pro) still rocking this device with the bootloader opened and a custom ROM, this was the first Android device for me, and even when MIUI was a letdown after a while, AOSP wasn't, still I go back and forth MIUI and AOSP though, it still gives me 6-8 hrs of SOT depending on the environment and the ROM.
Miyoo Mini V2, I just love to have pocket gaming on the go real quick, those annoying government formalities are not that bad nowadays.
College Education - paying to finish my 4 year degree, life changing
40mhz AMD PC processor /w motherboard. replacement for a christmas gift but it solidified my love of computers and computing. Which lead to my college degree and career.
Whole house fan, and it's not even close. We've saved tons of money by not running the AC as much as a result. Plus it just feels nicer to have fresh cool air come in from outside. I've even used it in the winter after the whole family got over being sick. Crack a couple of windows, turn the fan on, and the entirety of the house has fresh air in minutes. That got cold pretty quick, but worth having some stale air purged.
Drill press I'm an amateur woodworker who is apparently incapable of drilling straight holes.
Blackstone griddle A gift from a loved one who passed before they got to see me use it, but a nice reminder regardless. Works great for meal prepping something like breakfast burritos!
I'm either at my desk studying/working for a good 4-6 hours or I'm on my feet 6-7 hours a day. Keeping that in mind:
A really nice office chair. Perforated back, good adjustable lumbar support and head rest, quiet wheels, soft cushion.
One of those fold out sofa/bed things. Folds out flat into a giant bed, folds up into a convenient couch thingy. Better than a mattress to sleep on.
A good pair (or two) of shoes. Over the years it's been anything from a cheap pair of skechers to some no name shoes of off amazon to Adidas ultraboosts. Always try in person. Should feel as comfortable as your most comfortable shoes now.
Bonus: a good coffee grinder + v60 pour over + paper filters. Great coffee for under a 100 quid.
My girlfriend and best friend tell me it's the couch that I bought a couple years ago. I had a ratty old futon before that and they were not fans. I think it was from Room&Board, and wasn't anything special. Couches are expensive, though.
Although I do love my cordless drill as well. And my first cheap community college 2-year diploma which got my career goin, the jury is still out on whether the masters degree was worth it.
A corporation. Not like "I'm rich and I bought a whole existing business". Having a lawyer create an empty corporation and then buying it, so I can start a business. It was under two thousand bucks, not even the most expensive item on this list. Made back many times the cost.
The Huawei D15 is a good laptop at an excellent price. It's paid itself off many times over.
The Honda Air Blade 125cc 2021 model. Reliable transport at an excellent price, that has paid itself off several times over.
I also bought a used DSLR (Nikon D3200 for ~135$) to better document stuff I do, as a form of marketing. I pick up used, antique lenses for cheap as I encounter them. It's been profitable and generally great, but doesn't make top 3.
2002 Honda CRV I got nearly a year ago, been a fixer upper, but otherwise in fantastic condition for the price I bought it at.
Some iFixIt toolkit I bought off of Amazon, has come in real handy for many different things.
An acoustic guitar (Fender Dreadnought) I got at guitar center for nearly 200 bucks I think? Specifically wanted metallic strings, and it certainly has that. The high E string breaks a lot if I change tuning too often, but otherwise sounds fantastic and feels great to play.
DeLonghi Magnifica espresso machine about 12 years ago. The counter on my first one is at 30k+ shots. I bought another used one several years ago for the cabin, it has over 20k shots on it.
Pretty BIFL for a little fully automatic coffee robot. I'll be sad when they both pack it in.
Electric Mountain bike - i am over 50 and had not rode regularly since my teens. I borrowed a MTB from a friend last year and struggled to make any progress until I picked up a secondhand e-MTB. Since then I have been averaging around 150km/week and my stamina has notably improved.
PC - been a PC guy since 1989 and could not picture life without one. I'm an inveterate tinkerer and have built and rebuilt dozens over the years. I currently have a gaming desktop dual-booting Ubuntu and Win11 and a laptop running Ubuntu plus a couple of servers.
iPad - for years I was an Android guy but a couple years back I traded a spare laptop to my niece for her iPad (she wanted to learn coding) and was blown away by the user experience. Since then I have gone all in with iPhone, apple watch, and an old Macbook Air.
Just got one--a good, wide-brim, adjustable bucket hat. Shade during the sun, solid protection from the rain, comfortable, and not too difficult to make look decent, if not stylish.
Don't get me wrong, education, housing, health care etc have all been pretty important too, but hat wins.
I don't have a lot of stuff and not a lot of expensive stuff, but my top are:
Instant Pot. I have a tiny kitchen, so being able to do x number of things with one piece of equipment is amazing. Also keeps the heat down in summer instead of oven and gas stove.
Hiking poles. Got them recently, and they are a game changer. I've only ever seen older folks use them, but they got it right. Not only is it easier on my knees, but somehow they feel like they let me go further when I can use my arms as a little push forward.
Garmin Fenix watch. Keeps me motivated to keep moving, and it serves as a silent wake up alarm so I don't wake my partner in the early hours.
Honourable mentions:
A good hand-held flashlight. I use this daily for work and when I go camping. Also great at night when hunting mosquitoes in the bedroom.
A digital probe thermometer. Also used daily for work, and takes the guesswork out of cooking meats and things at home.
Steam Deck. I didn't think I was going to use it as much as I do. Thought it'd be something I use here and there, mostly for trips. I have a nice gaming PC, after all. But no, I use it at least a few times a week. Playing in bed, playing on the couch, sometimes even playing while I'm at my PC (which I know, makes no sense). It can play like 98% of the games that I want to play. And since it's a full fledged computer, I can easily run emulators on it, and even do work stuff on it. I tried working on it, with a keyboard and mouse. Screen was tiny, but it did work. It's easily my favorite handheld "console" ever. I hope Valve continues to work on this and perfect it.
