Well, once you learn the equipment, then it will be easy but here's a list:
Korg Triton
Akai MPC 2000, 3000 or 4000 (even the 60)
Ensoniq ASR-X, EPS 16+, ASR-10
Yamaha Motif
These are all sampling workstations w/ sequencers which is what you'll need. I would say go with any of the MPCs which you can find on eBay for a pretty good price.
Peace,
