Don,

seems there will be 4 options:

the most expensive, being the Deluxe,
which will require you to swap out your soundcard for the new VOCAL Hold feature.

i believe the $1,029 would give you the "higher" 256mb upgrade
instead of the standard 128mb, plus new soundcard, plus tons of other stuff

i will let AJ elaborate on the other options and prices, if he's ready to...
