] if you really help me ! Just do what some of the posters above recommended. Google the mining calculators, they will give you a very good start. I'm also a newbie, you must account for the bump ups in difficulty. As it is right now, the ROI (return on investment) will be a long time.
If you just gotta have one of the USB ones, buy it, but don't expect to make money with it.
