76 notes is only enough when I want to play an unweighted-action second/upper-tier keyboard now. I'm an 88-note man.

One of the best moves I made this year was to buy a graded-action 88-note controller to go with my 9000 Pro, and a graded-action digital piano for use when I am playing with MP3 backing. Now the leap to grand piano doesn't take as much effort and my playing is more consistant.
