Two appliances I got over 20 years ago that are still going strong:

Elna Funstyler sewing machine (that I've made multiple quilts, lots of clothing, and lots of repairs/random things on) (it outlasted my mother-in-law who poopoohed it because she had a Bernina that cost 10x as much)
Breville electric kettle that I use every single day. The light and auto-shutoff have both stopped working but it still boils water like a champ

I've started repairing clothing, and wow do natural fibers hold up so much better than synthetics, and they're much easier to repair. So I'm trying to only buy natural fiber clothing (unless it's something like leggings or compression shorts that are much better made from synthetic), which can be really hard to find for things like women's underwear.

I've stopped buying things on Amazon unless I can't get it anywhere else or need it faster than I can get to a physical store, and don't really care about quality. For example I needed a laser measurer in 2 days and didn't think I could make it to Home Depot by then. I used to get leggings with pockets on Amazon because nobody else had them, but now Costco does so I get them there. Amazon (both the company and the products) has gotten so shitty that I really try to avoid it.

I've had much better luck with Etsy, especially for household items and tools/crafting supplies. I just ordered two T-shirts from there and they were really nice quality and priced ok.
