I kinda want a couple of erupters just because they are so portable/cool? (or even just give them to friends to let them have a taste of bitcoin).. but at the moment they are quite overpriced.
I've been mining litecoin for awhile and switched to bitcoin (til the big jump). Messed up with the hardware and bought 3x 5770s.. should've went with 1 7950 or something instead.
