Emu XL-7 & MP-7 User's Group

I'm wondering how the mpc2kxl compares to the XL-7/MP-7 because I 
could spend about the same amount of cash for each now (of course the 
mpc would be used). I don't have "that" great a need for on board 
sounds, but it would be something nice to have. My main need is I 
need something to be able to sequence my Nord and my Supernova 2
(hopefully, still working out that deal). Anyone possibly have both 
machines, or used both extensively and could give me their honest 
opinion of both in terms of sequencing external instruents ? 

I want to make rap beats, dark techo and breaks, and light fluffy 
trance (yea I said light fluffy trance!). Also wondering if I should 
just save all of the cash and put it towards the pc+sound interface.
