It doesn't say exactly what condition they're in, or even if they work, but the price is quite reasonable:
CHERRY BLACK - G81-8000xxxxx CHERRY G81-8000 Keyboard Black$8.95 + 9.95 U.S. shipping; more than 10 available

Edit: Sorry, I thought these had Cherry MX switches, but they don't—they're
Cherry MYs.
Despite the negative tone of that DT page I just linked to, some people like MY switches, and these examples are certainly cheap enough to try one, if you so decide. So let's not turn this thread into an MY-bashing session, shall we? Cheers!
