Dennis,
You ought to check out the E 80 before you decide. It is like the G 70 on Steroids. I am back to enjoying mine after being gone for over a week in the motorhome. I was playing the Tyros 2 while i was gone and soon as I got home I started playing the E 80 and the difference was once more brought back to me immediately. I think I like the Roland better then the Yam but it will take me some time to learn the new OS system.
Best atcha
