If your just getting started, then I do suggest this I just found

http://www.ebay.com/itm/2x-Bitmain-Antminer-S1-ASIC-Bitcoin-Miner-WITH-POWER-SUPPLIES-180-200-GH-/281610915777?pt=LH_DefaultDomain_0&hash=item4191518fc1

And no its not mine



But if your planning on buy a s3, you will still have to get the powersupply and they are costly as well.
