Thought it would fun to comment on the OP's first post. :laughing:
We heat with wood. We live in the far north. It's colder than a well digger's grave. Which saw to buy is a lot like asking about Ford/Chevy/Ram or Orange/Blue/Red/Green tractors.
I also like having two saws. I keep them both in tip top shape at all times. Always use fresh fuel, (don't care about the other issues nearly as much) and always use top top quality oil. Do these things and take are of it and it will not matter if you buy an echo, husquarna or sthil. Some folks get half a life time out a machine even if it's a Craftsman/Poulan while in the hands of someone else the "best" brand will be trash in half that time.
FWIW, I like my lighter saws more with each passing year. My 30 year old nephew always grabs the Big Bad saw. I just smile. It's all fine with me.
