It if ain't a Stihl then it ain't nuthin'.
I've used all kinds and killed 'em too logging in Maine building log home from logs we logged on the property outside Taunton MA . Got galactically lazy and use my chainsaw to do all my wood splitting for the three cords I burn each year. Resawing monster logs into cants for breakdown in my BandSaw to lumber.
The closest I've come to killing a Stihl was when I dropped my 036 out of a tree from abut 50 feet & cracked the gas tank.
Sizing the saw to the man's uses is terribly important. Too small is bad and too large is going to be a permanent backbreaker.
What's he want to do with it?
Limbing small trees and maintenance around the house or felling trees and cutting them up?
If all he's going to do is light work a little Echo might be just the ticket. I've had an echo for better than 15 years and run the hell out of it even after I stopped climbing trees.
