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.

okay get an avalon 4.1 you pay over 500 usd it will run at 850gh and use .48 watts a gh. quiet quiet quiet.

you also need the older rasp pi to run it. so cost is 500 + a psu + 50 for the rasp pi. maybe 650 usd for 850gh and dead quiet gear.

so you are 650 out of pocket it burns .48 watts a gh

the s-3 with the mod and the psu you are 200 out of pocket it burns .8 watts a gh.

the s-5 is too noisy

the c-1 is pretty good choice see ebay links below.
