> recreating something like the Sunbeam T-20
I got a vintage Sunbeam toaster recently, and in the process I found this guy who restores vintage Sunbeam toasters for almost $300!
That's not including the toaster itself, which generally runs somewhere around $100 on eBay.
It makes me wonder if it's a better business to restore old toasters (and even other kitchen gear) rather than to make new ones. I haven't used his services ($300 is quite a bit more than I'd like to spend), but it seems like he goes to great lengths to fix up these toasters, even ordering custom power cords from a wire supplier. I bet it would be easier to start off recreating some replacement parts rather than manufacturing a whole toaster.
