Anybody played the Numa Compact?

I recently bought an Alesis Q61 controller, and I was instantly disappointed by the horrible action. The "piano-like" feel touted in the ads is accomplished by means of a spring which simply makes the synth-action keys harder to press down. Kind of the worst of both worlds. Pianoteq was the straw that broke the camel's back; it's simply too depressing to play such a potentially expressive instrument on a controller that would be better suited to someone who had lost his hands in a factory accident and had hooks instead (no offense intended to players with hooks).

Since I'm not primarily a keyboard player, I didn't want to spend a ridiculous amount on a controller, but I do want something that feels at least in the neighborhood of a real piano. I've read good things here about both the Studiologic Numa series and the Casio Privias. The Numa Compact looks especially interesting; I use a Yamaha MM61 live, because it's small and light and has a lot of features that are easy to use on the fly. I might consider dumping both the Yamaha and the Alesis if I could replace them something that would work for my live needs as well as in my home studio.

One more question, for those of you who are playing Pianoteq in live situations: do you have to carry an interface around in addition to your laptop, or do you use a controller which has onboard interface capability, so the sound comes from the keyboard outputs?
