Just wondering why you would want to move to a different keyboard. I got my PSR-740 in preference to the 2000 as I found it much more ergonomic for my personal style and the extra features and sounds didn't add anything for me. From what I can see, most PSR users don't use a tenth of what's available on their keyboards. I'm sure most would disagree but I wonder what they would say if they were really honest about it (and I mean REALLY honest - no strutting of male egos allowed).
