Another -often overlooked- benefit of buying used appliances, is that they have proven to be sturdy, and/or repairable.

Cheap temu-junk doesn't end up in thrift stores. Or, if it does, is easily filtered out. If I see a toaster that looks well used and/or aged, I can be certain it has at least proven to last a while and actual use.

It's also why I buy refurbished washing machine, refridgerators, etc: a refurbisher commonly won't refurbish stuff that's hard to repair: their economics prefer stuff that's sturdy, easy and cheap to repair. Win win win.
