ssmith pretty much told you all you need to know. Series 2 are better. Service every 100 hours is CRUCIAL. Personally... I wouldn't ever touch one. I know some people have had good luck. And I'm glad for them, I hope they last thousands of hours for them. But just way to many Yamipops out there... Nope. Not for me.
