Pipe, from what I understand, the 200 HPDI's are very reliable and touted as the motor to have. Shouldn't be any worries there.

I wouldnt over look a 250 or a 300 HPDI though... granted they have had problems, but most of that has been resolved and the motor's are good,,, Yama is standing behind them.
I'd definately get or have thrown in by the dealer an extended warranty and ensure the service bulletins were done and in writing.

I'm happy with mine, runs really nice and strong, pretty good on fuel too.
