I am grateful that Steve Demming is addressing this issue here on the forum. I am extremely satisfied with how my problems were resolved. Sweetwater let me keep my defective keyboard beyond the 30 day return (I was able to gig with it despite the problem with the Data Select Wheel), because there was a delay in their second shipment. And Yamaha accepted a return that I had scratched instead of telling me to get it repaired under warranty.

The 2-3% of unhappy owners sure make a lot of noise. Enough noise that I think it would be in Yamaha's interest to test these keyboards more thoroughly before they go out.

It is unfortunate that these many keyboards are defective, but I don't think it's a reason to stay away from this remarkable keyboard.

I have heard of two or three Europeans with defective PSR-S900s on the PK Owner forum, but the vast majority of owners are without problems.

The PSR-S900 really is creme de la creme. I am getting a fantastic response at my gigs. I think that it would be misguided to get a lesser instrument because of the fear of getting a defective PSR-S900. The two units that I am playing now - one for gigging and one for practice/studio - are very stable. No glitches whatsoever.

I am really surprised that the amount of PSR-S900s sold in the USA are in the hundreds - apparently less than 500. That's less than 10 for every state in the union! Of course, the keyboard has only been out for a little over a month, but that's really little. Yamaha being the most popular brand, it makes me wonder how many Ketron's sell here.
