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

Hey gang,
I'm perfectly happy with my XL-7's synth capabilities, but I wish I 
had more drum sounds. I've got the XL-7 ROM, the Pure Phatt ROM, and 
the Protean Drums ROM, but dammit - I just want more! There can 
never be enough great sounding drums for me. So that brings me to my 
question: I'm looking for other hardware drum machines with the 
following features:

- Grid recording mode
- Realistic drum sounds (a la the Protean Drums ROM).
- Ethnic percussion sounds - if possible 

Any and all suggestions would be greatly appreciated!
