what are you willing to buy a 1btc miner  or a 2 btc miner.

Or just a little usb stick miner  for 0.07 btc

or some thing in between.  the black usb stick miners in the photo do about 3.5gh

 I mine them at ck's solo pool and mmpool.org
One costs about 25  bucks shipped to the USA and one costs about 75 cents a month to run
