I think the best thing about the PA-80 (I have a PA-50)is the keyboard is completely customizable. You can move, or replace any style, or sound with a different one, and this is one feature I don't think Yamaha will ever incorporate. A person that is good with programming would like Korg over Yamaha, yet a person that doesn't like to program would probably like Yamahas over Korgs. I tried to get the best of both worlds by teaming a PA-50 up with a Yamaha Motif 6, and a digitech vocalist VR.
