If it has to be an MPC then get a MPC TOUCH. You will get the 2.1 software some solid kits, hybrid 3 vst and of course the controller. If its doesn't have to be an Akai machine get a Maschine MK3 which includes, the 2.7 software, massive plugin and Komplete select 11 plugins..
If you don't want to be tethered to a PC you can get a used MPC 1000 with JJOS and new pads anywhere from $400 to $650.
I have a MPC 1000, MPC LIVE, Studio (silver), Touch, Push 2, Maschine MK1, and a MK3. They all have there pro's and con's.
HE made this on a MPC X which is a standalone MPC like the MPC Live. The hardware has the same software (for the most part) as the MPC TOUCH/ MPCStudio controller when connected to a PC.
