Collecting vinyl records. I started 10 years ago when you could get lots of records for 3-5$ per record. Now everyone is crazy about collecting and they can cost 40-50$. Was a great investment if I sell them. But I enjoyed collecting them regardless of value.
Lots of towels and a big bin.
And for the turntable just pray I guess. I haven't figured out an answer for that yet other than my new one (from 1986) that actually has an arm lock.
So...I've actually had great success with LP boxes...(I'll look up which brand, I've bought two and one sucks) plus there's a company that makes a 35L XL plastic tub that holds records perfectly too. That one up at The container store. BCW is the best brand box...I've used them multiple times
