Its silly how much people pay for the Erupter Blades. I don`t support their practice of auctioning everything out either since they know demand is skyhigh. They don`t do it to help people make a good deal since it can never be a good deal. They do it to earn the most money on each Blade.
55 BTC for one Blade is just too much. Thats $7800 in todays price. It will take people about 3 months to just come out even. With BFL shipping units each day, with the many DYI Avalon projects out, its a really big risk.
