My little "jibe" at Dave meant only that he uses the keyboard differently from most of us. He often triggers vocal harmony with right hand chords and/or notes, while playing left hand bass. I don't need my keyboard to do that.
On another note, my local music store is going to quit handling arrangers of any kind. They say they spend too much time explaining, demonstrating, etc., and then very often lose the sale to an internet store who doesn't have to do any of that, doesn't have to pay a commission, and doesn't have to charge sales tax.
They can't compete on price with the Best Buys and Sam's Clubs on the low end. They feel it takes less time and effort to sell a $20,000 Yamaha Grand, or Clavinova than a PSR 550.
