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

Hi I'm relatively new to the whole music production thing I was 
looking at the MP-7 and the Rs7000 and what I want to make is hip 
hop/ 
R&b beats. From what I took in from reading about this is that RS7000
basically takes what the MP-7 can do and also has a Sampler in 
addition? Now, for my q? Can someone please give me an unbiased 
opinion on what they think would be more beneficial to me? Thank You 
all very much in advance. AS of right now I use only Computer 
software to make my music. BTW I really like the way the whole MP-7 
looks and sounds from the demos I've heard. please help me! =D
