As the title says, I'm selling my BFL Single SCs.  They're 0.7 BTC each and do not come with PSU but if you need a PSU I can provide a 850Watt unit for 0.1BTC (80+ silver rated) able to run two units or I can provide a 620W PSU for 0.06BTC shipped good for one unit.

I am tempted but BTC0.70 seems too high.

Is this the 60GHs model? If so, I'd pay .55 BTC for the miner and shipping to Ohio. Obviously the lack of a power supply and the older, less efficient chip design knocks its value down.

Well, it's available immediately and I'm including priority shipping.  I think they're great units for people looking to get into mining without dealing with more finicky hardware. 

This is actually cheaper than some recent offers I've seen buyers make on the forums so I think it's a fair price.

The stock BFL power supplies have had numerous issues and something like a cx430 costs like 20 bucks on sale so we're talking about a 0.03 btc expenditure to have a MUCH better and safer power supply.  To imply that I should reduce the price by over a hundred dollars because you don't get to have the unreliable fire hazard PSU is ridiculous.  Most techie folks will have a spare PSU capable of powering these.

My main concern is that if I plugged it in today, at .7 BTC it would only stay profitable until approximately early July and would only generate about $700 (1 BTC - energy costs) before the energy costs exceed BTC production. If I pay .7 BTC (approx $560) and then also have to buy a PSU for about $60, that leaves essentially no profit margin.

What part of the country are you located in, and what Gh/s are you getting on average?  By the way, how loud are these?

its a huge price, they will never make 0.7 BTC
