Scott,
thank you for your comments (I guess that you posted them while I was still elaborating my previous answer).
Frankly, I don't think that there are "jealous naysayers" here; I too have criticized the Tyros in the past, but this is a keyboard that you cannot just play for a couple of hours in a store. You have to take it home and spend some time with it (I did a lot of tweaking with the equalizer and the compressor and the difference was simply amazing).
Like we all know, there is not such a thing like a perfect arranger (or keyboard) for every situation; the Tyros (and the 9000 pro) are the best ones for the kind of music I enjoy to play in this time of my life, and that's all I need to know.
