I was asked to = troubleshoot some of these pianos for a local dealer. Bottom line, Wild pitch = fluctuations, warping keys, You name it, if it was bad ,these had it!The dealer told = me they were sending them all back. I know one was replaced with a Korean Kohler = that the client has been very pleased with. Warranty, Yes , replacement being = the only reasonable option, IMHO,but the piano disc will cloud the issue as = this is an after market addition and I suspect not easily moved to another = piano. In no way should any new piano fail as you describe .   Tom Driscoll</FONT></DIV></BODY></HTML>
