The way I see it, Bcu1525's are really cheap right now (over %50 off retail). As soon as good bitstreams hit the market all of the Bcu1525's and cvp's will be bought up and the price will rise again. If your the patient type, like I am, then you can actually save quite a bit of money getting your hardware now, rather than later.

I, like whitefire, can program the fpga's, making the hardware I have much more useful, even when it cant currently be mining with decent figures. Like bitcoin investing, it's a speculation and waiting game.
