Replying to MIDI MPC Choices/Questions

Okay so I've been making some musaac just using ACID Pro and that means i just put all the drum hits and stuff onone by one on there. This makes it sound kinda too computereized and sometimes its hard to sound right so i want to get an MPC and record bass and shit using that. So first of all, what would be a good choice for one? I don't want anything fancy, just something i can easily play the sample and record the drums on and get sounds on the pads from the computron. i'm a cheap-o as well
Also, can u use one of these bad boys on ACID or would i have to like get fruity loops and import the chopped sample onto there then do everything. I really have no clue about how everything works, i just try figuring stuff out on my own.
So thanky in advance!!!!
