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

Does anyone have the Pure Phatt ROM, and if so, what is your opinion? 
Is it a great ROM for hip hop, or would I be better off just buying 
an MP-7? How different are the Pure Phatt ROM from the MP-7? I've 
read a few times on here that the MP-7 and the Mophat ROM (the 
only "phat" ROM I can find is the Pure Phatt one) are different. What 
I would like to do is buy the PX-7 and install the Pure Phatt ROM 
(and maybe the Xtreme Lead v2 ROM eventually). Has anyone else done 
this? How did it sound? Sorry to keep asking so many questions, but I 
haven't been this excited about a piece of gear since I first heard 
about the MC-505 (years and years ago.....). The Command Stations 
seem PERFECT for what I'm doing.
