I had a Craftsman saw back in my other home when I had a wood stove and I replaced the saw with a Stihl and I could not believe the difference when I used the new Stihl for the first time. It was like a hot knife through butter. I would vote for the Stihl, but honestly I don't think you could go wrong with either. Echo, Stihl and Husky are all good names in the saw department, but I think Stihl has the edge! I have also heard that Dolmar is a good saw, but I have never seen any around here along with no dealers.
