Funny you mention this. I sent an e-mail to RCDriver in question since they advertise the hell out of hobbywing in their magazine. Since I have not seen them anywhere on the web or in stores I asked where I would be able to purchase one. Owning many hobbywing esc's, I like their stuff so I figured I would give this one a try. Here is the e-mail of the person RCDriver knows that does sell these in the states.
