I currently own a 2100 and am very pleased with it. Besides the megavoices, what would I gain by moving up to the Tyros? Since the 2100 is so very feature-packed, I wonder if a move to the Tyros would cause buyer's remorse. Now I know this is somewhat of a subjective question, but I know some of you will want to throw in your opinion...and that's what I want. THANKS!
