I was wondering if anyone had a dev board they were playing with? If so, what model? The only one I was able to find online was a monster 995$ 4x pci-e card with a ton more features than are needed. It also happened to be out of stock.
As for dev boards, the $995 is probably the "Avnet Spartan-6 LX150T Development Kit" (
http://goo.gl/S8oHN). This is a LX-150T board (note the T). The upside is that includes the ISE Logic Edition software, node locked to the LX-150T device. Normally the unlocked ISE Logic costs ~$3000
The cheapest board that I found at $750 is this:

http://goo.gl/LbCWuIt doesn't include an ISE LE license though, so unless you already own one (I certainly don't) you won't be a happy customer.
For volume orders (50+), the price of the EM6010-LX150is $649,99. Another price reference point for us perhaps. Still way above the design target cost for the Modular FPGA Miner.
