ive got an MPC2000XL, and its deffinatly easier to get a decent beat going + a lot more fun than using the computer... the process of putting the beats in the machine, then recording back into my PC seems to make the drums sound better (must a combination of MPC DA, cable, AD - PC)... you end up making drum patterns that you probably wouldnt have come up with on the PC drawing on the screen... you just bash the pads, straight outa your head in into the machine... the swing is really good on it as well.. pads feel good, well built, rock solid stability... 10 outputs..

FX arnt that great (really old S2000 / 3000 FX board) but they have character and are usuable...

And of course its great live as well, not to mention it can control all your other gear... 32 midi channels

I use this software as well to make putting samples in the machine a piece of cake

cheap as well, I couldnt live without it....

Id say buy it, if you dont like it for whatever reason, they seem to be holding thier value... so im sure you would have plenty of takers..
