if you click on the 11 sold button it shows that the ones sold were price at a mere $1090, lol
None have sold since the price increased to $3040 and if you look on ebay there are plenty of antminers selling in the 600-900$ range
Still making a decent profit though, and it doesn't change the fact that people will grossly overpay on ebay. Likely purchased for around $600 - $700 and mined for them a couple weeks before selling them. also, if you look back as his selling history, they sold an s1 a couple weeks back for $2390.
