Deane,
You won't be sorry with the CVP 609. I originally had a CVP107, then upgraded some years ago to the CVP307. I'm very happy with the 307. I sold my Samick grand piano because the CVP keybed was excellent and that it never needed tuning like my Samick 6 foot grand did 3 to 4 times per year. If I were to upgrade again( at this point very doubtful that will happen) I'd look at the CVP series with the GP tag to it. It's the one shaped like a grand piano that you played on the cruise, that's one nice looking instrument. I don't think the 600 series have a GP model yet, but not sure about that.
