I just started mining a few minutes ago after bitcoin mining being mentions. Sounds like fun.

current situation:

 I could see that mining can be lucrative, and interested in getting more serious. SO I was thinking about getting myself a BitForce 5 GH/s SC, not too expensive. Something I could "easily" miss. This thing earns itself back double in 1 month, if the MH/s calculator is correct. and perhaps get the 25GH/s after another 2 months.

So I've got a question.

anyone here that make his/her primary income from mining? because if I had a few if these machines, I would be making more than my current income. If the currency remains stable.
