wow, thank you guys, I could not have hoped for better: real pianist who give me their impression. I am studying piano although unfortunately, like for many of us, having a real piano is very impractical.

I do have a fully weighted keyboard that I connect to my computer, but it so happens that I really like Yamaha arrangers and they keep me away from the computer (a good thing!) and focused entirely on making music.
I can't connect the weighted keyboard to the PSR easily because I play in a small room and have to arrange the keyboards in a certain way.

So learning that the Tyros has a far better, semi-weighted action, is really interesting,I think I'll go for an used Tyros 2.

Scottyee, yes I agree about the sounds, quite frankly I think right now Yamaha arrangers offer the best sounds, and I own 3 Eastwest libraries so I am not easily impressed!

Just a last question guys, the Tyros has a better keybed than the psr-910 too, yes?

Thanks again!
