Ok, so I'm trying to upgrade my beat/music making and I'm looking at the Akai MPC. Mainly I want to make rap beats. I know that the standard is the 2000, but any opinions about the 1000, 2500, or 4000? Maybe ditch the MPC and get something different like a Korg Triton? Maybe get a used 2000 and something else with it. I am also looking for a good sampler which will make my samples sound better then when I put them straight on the computer. Any thoughts? I know that the MPC is a sampler too and will do that, but is it good enough?

Maybe I should use a good sampler and Reason?

I want to make very good quality beats. Thanks for your time and help.
