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

greetings, all. i'm a new member (and owner of an XL-7) and have 
already found this forum very helpful.

i'm considering a couple of expansion ROM's and an looking for other 
member's opinions. i've read a lot already on this forum about both 
Beat Garden (which i'll probably get) and World Expedition.  any
other 
ROM's that others consider to be essential? i do techno and ambient 
music. and what about the Protozoa ROM - $100 from Emu right now! 
does a sound set as old as this still have useful patches?

if you haven't already, call Emu this month. they're having a great
sale 
on stuff bought direct.

thanks
