Well, considering that a video card that makes 300 MH/s is about $150 right now (My XFX 6870 from eBay used cost me $70), I'd say it's a little hefty in the price range.  What does one of these draw?  I'm assuming about 5 or 6 watts vs a video card's 100 or so?  Big difference.

I'd like two; someone please point me in the right direction for participating in a group buy and I'm there.
