How is that hard to believe if in a month you can mine 9K at 6.5million difficulty (the next difficulty)
in two and a half months you're making profit...
Now why would you sell a money making machine that's beyond me...
Well, you can get an Avalon batch #3 for about $15K less - it will take more time, but are you really going to earn $15K during that time? And if BFL ships soon, this will lengthen the time to ROI. But of course, it may be hard to get a batch #3 since they may sell out quickly, and BFL may take a long while yet to ship, so I see your point.
My point is, who is selling an avalon when they can mine at least 9k for two full months.. and then probably 8k, 6k, 4k, 2k in the subsequent months of this year totaling somewhere in the ballpark of the 40-50k total... ( I could be absolutely wrong here as it's impossible to predict the future of BTC price and difficulty with all the variables in play, but you understand my point)
Oh, I totally agree that it is crazy to sell it (to the point that I wonder if the seller really has a batch #2 order). It's less clear how great the deal is for the buyer, but yeah, they will probably still make a tidy profit, assuming BFL doesn't release a flood of ASICs within the next month (not looking likely at the moment).
or BFL can flood the market and screw the buyer, etc, etc, etc..
