eBay item #130091982608 is a wonder: A mid '60s Eastern European bass keytar, built around a kind of Rhodes/Clavinet electro-mechanical reed piano mechanism, wrapped in nasty marbled blue plastic. It's $54 with three days to go. It probably actually sounds great. There's a nice long review of a Claviset (the daddy instrument this thing is based on) here.
