The problem for me with all the Yamaha P pianos is their 74 gram down weight actions aggravate my tendonitis.

My Roland dp-8 sustain pedal recently broke down and has some damaged circuitry so it only functions as an on/off switch for sustain instead as a half damper enabled pedal.
I have found that the full sustain tail of my P60 gets annoying after 10 minutes or so since it's the only degree of sustain being used. This dosn't happen with the Giga libraries even though they are not compatible with half pedaling (re-pedaling is the "workaround," something that I find that has to be done in regular quality pianos anyways.)
That's my only complain about my P60.
Yamaha doesn't sell the FC3 pedal in México and they suck for that :p

Good luck there.

What about the Canadian stores, like Tom Lee Music or Long and McQuade ?

Haven't tried them yet, but I got today a phone number from Yamaha Japan so I can contact someone at Yamaha México's offices that handle repair parts. A lady there told me that there's nothing that Yamaha Mexico can't get that is sold in other countries and that the people that I talked to first probably didn't want to bother by taking a special order just for a sustain pedal. So she asked me for the pedal model and that she will tell me if she can get it and sell it to me.
So, I'll wait for her answer and then I will try those stores, Me. American stores told me that they have agreements with Yamaha and that they can't ship any of their products to another country.
