honestly? goodwill. For household appliances, so many people get rid of old 1970s or 80s stuff that works perfectly fine but it just "looks" old. You'll have good success if you go to a goodwill in the suburbs if possible. I haven't bought something new in like 5 years now at least. I've got blenders, food processors, crockpots, waffle irons just you name it that are old, and well made.

basically less technology is better for most of these things. i don't need an LED display on my waffle iron, i don't need programable crockpots. Less shit to break
