hi jeff,
i'll give you my 2c.
my bro is a prof. tree guy, in the business over 30 yrs. his crews solely used echo for small tree work.....stihl or husky for large tree work.
he steered me towards a echo (3450 i think) came w/ a 12-inch bar, it'l also run a 16" bar which i tend to use more often.
i've had it 10 yrs, use it ALOT, and it still runs like a screamin banshee.
