Silitek SK-8802B-1 (eBay)
I just restored one of these (
see topic here). I received it as a free bonus with another board, and was pleased to discover it had vintage Cherry MX Blues.

It has the small Backspace and "big-ass" Enter—but if you don't mind that (see the topic for my take on it), it's a very nice 'n' clicky board at a bargain price!
