It is by far the best stickminer on the market. OP sounds like he want's to mine alt coins... there just are not a whole lot of sha altcoins. Bitcoin is pretty much most worthwhile to mine.
As far as altcoins LKETC has a usb stick for scrypt but it's pretty small power overall. It would allow a lot more altcoins but I would just mine BTC for fun off a compac if i was choosing what to do.
I predict compacs hold value better then the LKETC scrypt usb stick miners.
