If you ever go to India, take an extra suitcase that you can fill up with Stainless Steel cookware. The price is amazing, and the quality is so much better than what's available in America. We spent about $85 on what I estimate would have cost $400-$500 in America.
Not in the US, but yeah I do know a little Indian warehouse with a pretty extensive selection of stuff. I find myself preferring aluminum just due to the reduced weight, though.
Oh, I don't really recommend copper as someone that cooks.
Like, you can accidentally poison yourself or possibly give yourself early dementia. They are a pain to clean unless you are willing to buff them constantly to keep the shine... Do yourself a favor and get like a couple decorative pieces if you really want copper but cook with steel/iron
Oh..... Yeah... Good luck getting it to keep that lining.
If you want to do it for just the experience go ahead but also still don't cook with it.
Tin sucks. Like straight up. Super soft. Scratches easy. Melts easy. It's not nonstick and things will stick to it and the act of scrubbing it will potentially strip the tin off and make you get to enjoy relining it again, and again, and again, and again and...
Copper is pretty, but you'd have to really put a gun to my head to make me want to cook with it ever
