I've recently purchased the parallela board:

http://www.parallella.org/

It's got USB/ethernet/arm cpu , and has been incorporated into numerous other projects. It's ~$100.00 USD.

I second the parallella, not only does it have an FPGA, an arm core and a massively parallel cpu. So much to play with and still running Linux so the workflow is super smooth.
