Have you looked into the M-Audio Keystation Pro 88.
USB - 88 keys, hammer-action...a gazillion buttons, knobs, and sliders that can be programmed to function for any of the control options you'd need with a sample/composition set-up.
And the kicker...its cheap.
I just got rid of my Roland A-90 and purchased one of these and the VSL Pro Edition. I love them both. It's amazing how much more I enjoy some of piano libraries now with this controller...you can really tailor the velocity curve to your own playing and end up with a great set-up.
Here's a link to some info:
