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

Hey I got here by looking around on the E MU site.I do not currently 
own the XL-7 but Im seriously thinking about getting one (or the XK-6 
Extreme Keys keyboard). Right now I mostly use my Yamaha RS 7000 and 
yamaha keyboard. Im looking for some new sounds (mostly Orchestra,  
Pad sounds, and more drum kits) and listening to the demos for the E 
MU I was impressd.I dont like Roland stuff and the Karma was my only 
choice with Korg (but thats $1700 !).How satisfied are you all with E 
MU products and is it pretty straight forward to record patterns and 
songs? And when you put an expansion card in, does it just add more 
sounds to what is stored or do you have to switch and choose?

Thanks!
