I’m in the market for a top notch toaster from the 1950’s or 60’s. I live close to a very wealthy town, and I have no doubt I will find one at one of their local thrift stores, as most of the possessions of those wealthy people, when they have passed on, go to a particular thrift store. I have had several cheap toasters over the years, and not a single one can make a decent piece of toast. I don’t think I would have had much better luck with a more expensive model, since they just don’t make things like they used to. Except for Speed Queen washers: they’re still top notch.
I never have success going to the thrift store with anything specific in mind. But I’ve gotten lots of really nice vintage stuff very cheap, by routinely browsing the stores.
