Scott,
I can answer for 3 PSR2000 owners. Two of my friends ordered them after seeing mine.
Two of us play just about every night and the other every weekend.
As you know, I am a full-time entertainer, and the other two guys are "week-end warriers".
In fact I've played both the other keyboards on the job recently and can report no problems whatsover. They both play harder than I do, but not quite as regularly.
When I go to one of their jobs I can just slip by floppy in and start playing.
All keyboards were bought before Jan. 1.
