To the mechanics on here... how often do you actually see snapped or jumped belts on any motors? Maybe I'm just lucky but I wouldn't bother with the belt.

It is complete and utter foolishness to skip timing belt replacement. Honda's are tough and have a nice wide timing belt, that will probably go longer than the maintanence interval, same with Toyota, and Nissan, but man, once they snap, you are out a motor. or at least an expensive valve job.
I always tell people $600 now, or $2500 later .
I see it more than you would think, but I always push timing belt service on my regular customers, so it is a little more infrequent with my regulars.
No way would I risk it much past the interval, water pump, tensioner, or roller failure will also put you out of commission
