I think if someone is willing to pay more than 300$ for it, then they are pretty much dumb.
Trying hard to understand this one?? I get difficult is increasing, but this still made over $160 in the last week.
Because in another week's time it'll make about 1/3rd that. Here's a good rule of thumb which is only good until the next difficulty jump:
A. If you're wanting this to break even (at the least) mining BTC, then don't pay more than $300-$500 for it.
B. If you want to a collectible which does nifty stuff and helps warm a room and don't care if it breaks even, then pay any price up to $1000
C. Any 60GH unit over $1000 is just like rolling a joint in Benjamins. Sure it's neat at first, but after awhile you'll feel the burn, unless you don't care either way.
If it were me, I'd be concerned with breaking even/mining up until it's no longer profitable with BTC. Then go mine altcoins fast as hell and hope everything goes up in price over time.
