I'm ready to trade in my old Stihl 011 saw and my dealer suggested the Echo CS-440. He carries Husky and Echo and likes the Echo because it has 2 piston rings and a 1yr commercial warranty. The Husky only has 90 days commercial and 1 piston ring. I want a little bigger saw with an 18in blade. I don't do treework other than occasionally taking down a dead tree for a customer. I do trim palms quite often. Does anyone have this saw and if so, how has it held up for you?
