Has anyone actually seen one of these mythical beasts in the wild?  I'm having difficulty purchasing one.  Perhaps it's because I'm looking for a self-powered USB drive?  Constraints of the server room require that we not plug these things into their own outlets.

Any suggestions for buying one these things to use?  Anyone have an experience with one they can recommend?
