You said it STephen , I just don't understand why guys like you, and I mean professional entertainers like Donny, DonM, etc.etc. simply do not hang on to both makes. I wish Donny all the best with his PSR950 ( I know I like my 750 for playing at home) but still think that if you can afford it and have the musical talents as displayed by the folks mentioned it is a shame to get rid of either keyboard. Seems to me that a PSR950 with a PA3X is a truly killer combination, even on the road. I know the Tyros is even better ( than the PSR950 ) but more convenient for studio/home use.
I have said so many times, just get the best of both worlds, whatever your purse strings allow you. PA800 + PSR750 works fine by me....
