I am considering buying one for $1500, but after reading these posts and looking at the rising difficulty, it doesn't seem like it would really be worth the effort in 3-6 months when difficulty has increased 10-fold more. Now I am thinking $1000-1200 is a reasonable price point, considering the payout and risk. They are selling on eBay for about $1500. The prices are falling literally every day locally as buyers become more scarce. My guess is you would be lucky to get $1500 by mid-November.
