You all seem to be approaching this from a different standpoint.

I'm not looking to mine and make a killing off of the profit/roi. My goal is to find something with a ratio of 1gh/1kwh or better (consider that... hardware = sunk cost, profit is on a real-time level per coinwarz SHA256 calc). I'm an independent, self-employed individual with a bitcoin 'hobby'. My electricity costs are always written off as business expenses, so if it jacks up my electric a bit then it's not much of a problem. My goal with the BTC will be day-trading, and various forex.

I hope this can better guide the opinions and suggestions.
