Fran, the Roland G800 I had started falling apart a month after I bought it. The spring in the Joystick broke, the buttons started sticking and getting to where you had to push them very hard to make them work. Even the paint wore off where you had to remember what button did what. Maybe they improved all that in the G1000. Or maybe I had a lemon.
Anyway, in all the years I've played Yamahas, with assorted side journeys with Ketron, Korg, and Technics, I have never had one mechanical problem with them.
Not being a piano player, I also don't like the heavy keys. And even when I had onboard speakers, most nights I disabled them.
Isn't it great we have so many choices now?
Anyway, your compromises are different from mine!
