thank you for your advice on this.
I did try the korg pa3x and felt the yamaha was better sounding on the backgrounds (korg sounded kind of "thin"---but that could also be due the fact no one knew how to operate that keyboard.
tyros accompanyments sounded very good and was fairly intuitive. What I didn't like about the tyros was the number of layers you had to dig through to get to certain functions (and again, no one really knew how to use it)
It was hard enough to find a place that actually stocked the tyros 4 on the floor to try....it is damn near impossible to find an audya to try in real life.
With regards to the audya I have a few more concerns
1) is it hard to see the screen since it doesn't tilt?
2) has the latest operating system pretty much solved all the problems with the audya(I'd probably be going for the 61 key model)
3)does it sound as good "out of the box" as it does on youtube (abaco62...aka jack canon...makes it sound like a LIVE orchestra)
3)
