I recently bought one from New Jersey for a student in almost new condition for $2,100 including shipping. There is no discernible wear on any button or key. So your price of $2000 is probably a good number. There are two on eBay now but they are not in mint condition.
Hey Bob ! Thanks for the info. Mine looks like it just came out of the box.
I really hate to part with it as it sounds just so darn good. But I can't justify two keyboards sitting around, especially since I'm just a casual player and don't do any public playing.
Actually, I have a KN2000 AND a Yamaha PSR-SQ16 as well. Both in perfect condition.
That Yamaha SQ16 was top of the line for these "easy to play" keyboards. Yamaha was ahead of the curve on this and it has some really good built-in tracks. It was/is more difficult to use than the KN series of keybopards.
