Hi Paul,
One of the reason I didn't buy a PSR 9000 was that when I played it the styles and variations were very simple including the intros and endings. The weight was another big factor "Too Heavy", besides the inferior internal speakers sound at max levels. This really surprised me, as i was excited to play the 9000 that day but my excitement dwindeled in a half hour in the store as I went thru all the syles one by one. But thats my opinion only.
