As you've probably already heard, BFL offered credit toward purchase of their ASICs for those of us who've been waiting for preorders to arrive. I have eight available, worth a total of $200 off the purchase of eight ASICs, assuming you're willing to buy at least 100 (or go in on a group order). I'm more interested in buying completed miners ready-to-go, though...besides, I don't have a reliable way to assemble BGAs and nobody's worked up an open-source miner around these chips yet (other than BFL, of course). I'd rather have money to apply toward buying more miners.
Here's a screencap of my available credits:
I think
BTC1 is a fair price...it's about 55-60% off of the value of the credits, at current exchange rates. I've not done a huge amount of trading, but I have a #bitcoin-otc rating and a few purchases on Bitmit that have gone well.
