OK, so i got in to reading a bit about this mining stuff, and thought i would try it out. Aaaand i was struck instantly, and now i want more! I have an Nvidia gtx780 in my computer (my only computer), and it is achieving TERRIBLE MH/s, only about 300 at best. So i was thinking of getting a usb block erupter, because they seem like the most cost/power efficient way to mine for Bitcoins?
I was looking at the Bitmain AntMiner U1 with 1.6GH/s, it only costs about 65$, but are they any good or are they a scam? Because they seem a lot cheaper than most other usb block erupters out there, which only give around 300MH/s at a 35$ pricetag.
