I have a friend who owns the Roland FP9. A bigger contraption, it has the Roland hammer action keys and features a sampled Steinway a couple of other sounds, a few special fx and little else. It sounds pretty good and feels pretty good. I think it goes for around $1800.

But in my studio, I have a Fatar SL 880 ($600) controller hooked up to the computer with a 2 gig Gigastudio grand ($300 total). When tweaked properly (to velocity #2), the Fatar feels much more like a real piano than the Roland. It has splits galore and velocity control for each split. Does the FP-3 have a newer design for its weighted keys than the FP-9? If not, I must say that I have never felt and heard a more real digital piano than what I'm hearing now in my studio. It's not perfect, but I often have very soulful experiences playing this setup.
