I found a 6-slice Dualit toaster here in Hong Kong. Dualit is the UK version of the Sunbeam, very expensive when new and a favorite of professional chefs -- all heavily chromed and polished stainless steel, all hand-assembled. The kind of thing that you can strip down by hand, clean and polish and re-assemble, and you have essentially a brand new toaster, even if it's fifty years old. (Of course, any heating elements may eventually need replacement, after umpteen heat/cool, expand/contract cycles.)
Unfortunately, the 6-slice model is way too big for our current (small apartment) kitchen, but I keep looking and looking for the 2 smaller-slice version (about like those Sunbeams). I did find a decent Chinese copycat in real steel, but it just didn't have the same quality, so I passed on it. One day...
