I've had one of these for quite some time now, and it looks pretty much the same except more expensive and without the foot pedal option (great idea!)
The important thing is the software rather than the hardware which is meant to be able to detect the curvature of the pages on a bound book and adjust for it. It sort of works most of the time on the SV600 but it's not especially fast and neither is it entirely reliable.
I gave up on it mostly because the software for the Mac was pretty unreliable. I do note they release updates for it very regularly so maybe I should try it again as I haven't touched it in over half a year.
