For about the same price you'd get the Roland A-800 Pro, which I'm also using (amongst others).
The A-pro is recognized in Sonar as a control surface, so it has got a functional set-up that you just dial in once with 2 mouse clicks.
Then you got ACT control + transport + standard MIDI stuff + keyboard split + more, all readily set up for you ... plus a fast MIDI link via USB ... I'm quite happy with mine ...
