MPC or Software?

Yo,

Been thinking about an upgrade to my productions this year - the last few years i've been using the cheap ass software, Fruityloops, and for about a year now {13 months or something, from scratch} i've been using Reason 2.0 and I feel like i've pretty much explored all of what Reason has to offer. Check some of my 'ish at www.esskodebeatz.co.nz. Its mainly hip hop and a little dub.
Anyways - if you listen to what i'm producing now with Reason, what do you think the potential would be if I bought an MPC 2000xl? Would this be a step in the right direction for my producing?
I've been a musician for a while, and i feel i know my way around producing and what goes into it quite well - however, i've never laid my hands on an MPC before, are these fine peices of equipment exceptionally difficult to use, or is it all in good time sorta thing?
thanks!

hey man i love your tunes , really nice bit manuva style .
i dont think you need a mpc in fact i couldnt realize you are using reason , cus mainly reason sounds like reason , but if you stick to the computer for sample editing you could do that with a mpc too .
but your stuff is grooving anyway .

if this is reasons then maybe I need to jump on it ....beats are fat, no need to get an MPC
