Are Stihl MS180 chainsaws worth a flip ?

I bought a new Stihl MS180 chainsaw in March 2009. Started it today 13 months later, note that it's one month out of waranty, and it blew a hole in the top of the piston. This saw has not even had one gallon of gasoline ran through it yet. It's been used very little. I'm not impressed at all. Are these things known for being cheap, short lasting or is it a fluke that I got no more use from mine as I did. I will get in touch with the dealer Monday and if they don't make it good even though it's barley one month out of waranty, I'm going to go to Home Depot and get an Echo brand. At least they have a 5 year waranty ! Thanks for any legit replies !
