Echo is generally a good saw. The new ones have the same problem as all the other new ones: EPA has made manufacturers lean them out so much to meet emission standards that they run hot and at less power than an equally-sized saw from just 5 years ago. My little Echo CS-360T is a great one-handed top saw. I have an OLD Echo CS-510EVL that is a monster, and I run a 24" bar on that one. I've put about everything new in that saw over the years. New plastic tanks, on/off switch, fuel lines, rear handle, stuff like that which is from lots of hard use and the crappy fuel we make now. Keeps on a-runnin'. The Stihl MS391 I bought new, runs OK after it gets warmed up, always takes 5 pulls to get it running when dead cold. 1 pull after warmup.
