I have been asked to head up another bulk order of my SBC-2 boards. I would be happy to do so if there is enough interest. Board info can be found here:
http://sbc.rictor.org/sbc25/info.html

My cheap source of serail tail cables went out of business, but they are easy to build if another source cannot be found. I can also provide programming support for 28C256 EEPROMs or 27C256 EPROMS to support the board. However, I do not have any 65C02, 65C22, or 65C51 chips. Mike Naberezny can provide the first two, and the 65C51's can be found at a few online sources.

An order of 10 boards would be ~$23 each.
20 Boards would be ~$19.70 each.
Shipping would be $5 for priority mail for any qty of boards.

Please contact me via email or PM if you are interested.
