Digilent has a good collection of low cost FPGA boards:
The Spartan 3 board (down at the bottom) has 3 40-pin connectors plus RS-232 for $139. Beware, the big connectors don't have many grounds. (I'd probably turn the board over and turn half the pins into grounds.)
Their Add-on-Boards might have something helpful if you the board you pick has the Hirose FX2 connector rather than something simple and low tech.
These are my opinions, not necessarily my employer's. I hate spam.
