Antminer S1 is a good unit, It runs stable @ 180GHs = 300w overclocked to 197GHs at about 370w. I have S1 - U1 U2 - BFL 8G 12G & 30G cubes. One factor I look at is power consumption, With a $0 power bill, you can use the fastest GHs miner without power bill worries. People misunderstand Mining profitability, don't look at value vs. BTC today. look at coins created. The coins I mine today .024 BTC per day ($11.38) will never cover a ROI, in 5 days - weeks - months the same coins MIGHT be worth $5000 each but, in 5 months with difficulty rise I will only make .001 BTC per day with a %20 rise. This is why the .024 is is a good investment.
