Yeah, that was my best guess as well

That's all according to calculations.....
However right now the offer is
20 GH/s mining for $150 US
your reward accourding to alloscomp mining calculator will be 0.15187812 BTC or $146.11 US at gox value. If the price rises to $1100 within these 30 days your output will be (approx) $167 US
Keep in mind that you do not have to pay for power usage either. But make your own calculations

Thanks for being honest and putting the figures out. For the price to have to be $1100 to make a small profit though is not a good bet IMHO. If you think the price is going to $1100 you might as well just buy bitcoins now for $850 and make $250 profit.
Indeed. This topic doesn't even make sense/profit.
Well, it only starts making no sense when the OP revealed the "profit outlook" - otherwise someone might have jumped in, though more likely on eBay, where people overpay for everything BTC related
