I just received a $130 check from MasterCard for the repair of one of my PSR-S910's. The headphone output and audio input were not working. I brought the keyboard in 3 days before its second birthday.

Earlier in the year I received a check for $105 for the repair of my other S910's pitch bend wheel, and before that $59 for an intermittent problem with the mic input.

Two and a half years ago, I received a check for $350 for the repair of one of my S900s that needed an expensive part.

I highly recommend purchasing your gear with a major credit card, and if it fails after the warranty is up, look into the extended warranty service offered by your credit card.
