Maybe I was a bit blunt. Back to the original question:

The 500 does not map with the 800 - period! I put in my song sets and it was a disaster. I spent countless hours trying to make it work, to no avail.

I agree that the 500 is a very good sounding board, but misses many elements of the 800 (IMO).

Donny - quit messing around and go with the best - you deserve it!
