I bought my PSR9000 24th January,2002 so I have enjoyed playing it for over 10 years!
To me , it was a "wow" of a board after a couple of earlier Yamahas.
I still have my 9000 and only now am I stirring to get a Tyros 2......
I suppose the reason I have stayed so long with my 9000 is because I am not an accomplished
artist like so many of the members of this forum.
I amaze myself , and my family sometimes, with the great songs I can produce and gain the admiration of them.

And that is why I have continued to improve my playing and song writing for so long on just one now outdated board!

As spalding1968 has remarked, the changes did not come until we heard the Tyros range (I of course mean only the range of Yamahas)

And so I will probably be owning a T2 in the near future..... But I don't guarantee it !!!
