Hi Everyone,
I use a Psr-3000 and I am thoroughly satisfied with it.I actually have two,one being a backup.
In regards to Gary's comment that there is more polyphony on the Tyros than the PSR-3000,that is not the case.They are the same 128 note polyphony.I have heard the tone generators are very similar,and the major difference in sound is the more elaborate speaker system of the Tyros,but I have been unable to confirm it.
Having had a 2k and 2.1k, I can say the 3k is light years ahead.It is less fussy to set up than the Tyros and it's extremely light weight make it the ideal gigging keyboard.
