In the case of the PSR2000, I wonder what the 'extended warranty' will actually cover. The warranty does not cover physical damage or problems due to normal 'wear and tear'. My biggest concern is the keys eventually giving out (breaking? :eek) or buttons contacts wearing out. I bet Yamaha may exclude these things from coverage as 'wear and tear', especially beyond the normal warranty period. I guess only time will tell. Keeping my fingers crossed. - Scott
