Advantages of Butterfly Labs chips:

•    1/10th the silicon area per GH as the closest competitor (Very high performance density)

Details

This group buy is for a total of 100 Butterfly Lab ASIC chips. Once the total paid orders reaches 100 chips, the group buy will be closed and any remaining participants will either be refunded their order amount or be given the choice to participate is a subsequent group buy. The remaining amount of chips will be updated in this thread.

Once the group buy is closed all sales will be final. While open, refunds may be requested, but not when closed.

I reserve the right to change the price per chip as BTC is a fluctuating comodity and BFL only sells their chips for US$.

Shipping is not included and any import/customs fees are the sole responsibility of the buyer. Local pickup is acceptable Detroit, Michigan, USA).

What can you do with the chips?
Build an awesome bitcoin miner of course!
They can be placed in unpopulated chip positions on BFL (Butterfly Labs) mining boards. (I will offer this service once I prove it can be done on my own BFL board)
They can be used in DIY or open source BFL type mining boards
