Thanks guys!
I don't play the guitar or anything but keys. And even those not very well, hence the need for auto-accompaniment :-(

Newb, just like every battery-powered Yamaha since the '90s, the PSR-EW400 doesn't allow a player to specify "on bass" or slash chords.

Bachus I haven't seen any Vivo / Dexibell products for sale here in the U.S., and the lightest model I could find on their website checks in at 22 lbs.; more than a Roland EA-7 which is about the lightest arranger currently for sale with built-in speakers.

Thanks for the feedback, but I'm surprised more folks haven't commented on the items in my original list. Keep 'em coming! -Ted
