Not to run, but as an initial purchase. power is not an issue although i cant run more than 1000watts.
okay sounds like you have very cheap power up to 1kwatt.
if that is the case get a pair of s-3+ miners and a decent psu down clock them a tiny bit to freq 206.
they will pull 660 watts and hash at 850gh for the pair.
sidehack has a decent psu and pete from gigaamz has a good psu

this psu will run 2 s-3's and use around 640 watts if you underclock

sometimes antminers s-3's are as low as 90 bucks even 80
you should be able to get a psu and 2 for 300 or so. if your power is 3 cents a kwatt you should make a profit.
