Finding a used EZ1KUSB

I'm trying to replicate a laboratory setup that a coworker is willing to share with me, but in order to do so I need the EZ1KUSB-50 board that was sold by EasyFPGA. The board is profiled at this website (http://www.easyfpga.com/ez1kusb_features.htm). Unfortunately the company seems to be no longer in business.

Is there anywhere I can go to look for used old development boards or does anyone on this thread know where I can obtain one?
