Reply to Controller For Reason 4.0

I'm planning on replacing my "generic" studio midi controller (currently using an older & bulky roland xp-80 workstation which primarily controls Reason 4.0) with something that is much smaller & better mapped out to Reason with velocity sensitive pads and faders etc. I run Reason inside Ableton Live 7 (just pre ordered the MPC 40 for Ableton). Would anyone have any good suggestions as to a good match for this studio setup w Reason? (I've been eying the soon to be released M-audio Axiom Pro series...Any drawbacks with Axiom series...Is there something that may be a "better" match)
Thanks for any input!
