Damn blokforge is starting to annoy me. They just pushed the 741 / 821 order date a week, to January 2, same time. I've been emailing with someone at blokforge, and they are limiting everyone to 2 miners of any model. Now I got to wait ANOTHER week, DAMMITT!!!!!
I've done a cost / benefit analysis on the 821 and 841, and they are both far better than the 741 for power usage and hash rate. I don't know why anyone would waste money on a 741 at this point. And ebay prices are simply ridiculous. Those commie bastards at Canaan jacked the price to insane levels. I'll keep trading bitcoin on the highs and lows, add my tax refund, and buy a bunch of 841s in a few months.
Current pricing for the 821 is $1850, Canaan has it commented out in the HTML source code on that page of their site so it does not show yet. Looks like they are trying to squeeze every penny out of the 741s.
1850
?!!!!!! the reseller pack (60 miners + 60 controller + 60 power ) = 174 K$
so a working unit = 174/60 = 2900 $ for the reseller + shipping fees + profit for the reseller = NO WAY 1850$ the unit
