Don,
Since my surgery I have zero control when I try to sing. Somehow they messed up my vocal chords. I saw some demos of software for pitch correction but can't find them for some reason. Anyway, I haven't messed with the VH yet.

Joe, I played tonight with the S950 - everyone loved it. Easy to move, thousands of styles to select from, and pretty nice sounding out of the box.
For me it is winner.
