I would NOT part with my 7000 at any price. I satisfy my urge to try the latest, by getting a "second" keyboard, and I don't buy the top of the line for that. I bought a PSR3000 a few years ago, then bought an E50 recently. It's fun to have a new keyboard to mess with, new sounds, styles etc. The KN7000 just seems to be above the others so it's not going anywhere, hopefully it will not breakdown!
