Echo I don't know the modelnumbers, but they have a strong following of users. Not the top but enough and very economical on fuel as I read from other users.
Efco has a strong following of users. Not the top but enough.
I just got a very good deal on a Solo 644 (45cc, 3,5hp, 15'b&c).
Very nice!
Please do not fall for the critic that you might recieve from others that your saw is inferior because you cannot do nameflashing! A saw is there to cut not to reenforce your ego!
I used to have only a Stihl ms 180(generally thought as underpowered girlisaw around here until
blsnelling proved otherwise) and cut everything with it. (here's a video from me) It might be slower but the job gets done! The
only important part!
