Hi///I never owned a kn7000, but I did have a kn 3000& kn6500,I was in love with my 6500,so I bought another one on e-bay,when it arrived it was junk,I sent it back and thanks to pay pal I got all my money back, all I wanted was a good back up 6500,well I'm glad it was junk, I then got my pa800 and still had my technics, at first I hated that pa800,I was ready to throw it out the window a few times, just so different from the technics, well I played & worked on the korg,now I love it. I now have sold my kn6500,I really like the PA800 styles and the songbook is great... etc.I'm still learning but I like it more& more every day( I DO NOT MISS THE TECHNICS) it was a great k.b for it's time///PAULA
