I want to try to start making money with bit coin mining. I have used a bit coin calculator and I would make money and lose none over 12 months. I have found one (http://minersource.net/products/bitmain-antminer-s3-available-july-26th) and a psu (http://minersource.net/products/thermaltake-smart-series-sp-750m-750w-atx-psu) but im wondering if I should follow through on this. My electricity costs are about 0.13/kWh. I really want to buy one too. Im worried about the bitcoin market. I cannot predict what will happen but im assuming the flow is controlled so it doesn't inflate or deflate. Im still new to bitcoin mining. Should I buy it? Thanks And Could someone link a guide/support link to the Antminer S3 if there is one?

I am looking to buy a bitcoin miner for a cheap price. I was really looking into a butterfly labs 10GH/s for $250 Link(https://products.butterflylabs.com/homepage-new-products/10-gh-s-bitcoin-miner.html) Is it worth it? I know a decent amount of information about bitcoins and such, but I dont have a big budget here. Only about $600 Max. What should I get or should I get one? If I get one I will be joining a pool. But how much bitcoin(s) can I make which a certain amount of GH/S? Thanks and I wish many bitcoins to you!! Feel free to respond and give me advice.
