thanks for the quick reply.
Really keen on starting this so was thinking, I could just get the amount I need to start mining by purchasing the lowest amount I need for 1GH which is 0.01250000 from say BTC-E and then add more hashing power later.
Is BTC-E a trusted source to purchase BTC?
Sorry for the questions, as you can tell I'm very new to all this but am learning and reading all about BTC.
thanks again.
