MANY Asic usb stick buyers on ebay (I resell some sticks keep some for me) can run a small hub with 4 sticks or even a 10 port hub in a free power setup. Think dorm room. A 7 port hub link this one.

will run 7 asic miner sticks at under 30 watts.
1 blade needs 70 watts . It is not plug n play on bitminter's java client. A lot of ebayers use doc h's java client
So if someone has 7 AM sticks running right now on free power. selling one of these will be an easy sale plug n play.
More then 500000 AM sticks are hashing at this time worldwide. these will sell they are a natural upgrade to any AM stick owner. I do agree that .49 btc is high 7 am sticks cost .245 btc half the price.
These could be lower priced if they can make a lot of them.
