Thanks, they messed up the link in their announcement.
i was just curious...price is too high...good for the aftermarket, though.
Your cost=1.16 btc (1.115+$54 shipping=$1410)
7.81% difficulty rise=super bad (produce only 0.83btc total before going nonprofitable at 7c/kwh)
4% diff rise=produce 1.5 BTC in a year (still $425 in $deficit), so you depend on electricity cost below 7c AND bitcoin being stable or going up. No safety.
I'll pass for now.
