My Echo currently has a 16" Poulan bar and chain on it.I started to mention the Echo. I have an Echo power pole saw, which has done well, after I put an Oregon chain on it and I have the Echo string trimmer you recommended, which has also done well. I think Echo has caught up, especially in the moderate price range...
Every year as the holiday season approaches, Walmart drops prices on all the lawn and garden items, including their chainsaw components. You can pick up bars and chains for really good prices....which I have done. I messed up my old 18" Echo bar last year so was able to switch over to the 16" Poulan bar very easily and for the work I use it for I don't really miss the 2". I picked up a couple twin packs of the same size (16") chains very inexpensively when I got the bar so I'm set for a while.
I really like the Echo line of hand-held power equipment. I have their blower, weed wacker, edger, and drill all in 2 cycle. I use the drill to drill into landscape timbers for the rebar to hold them in place.
But there are plenty of other options as mentioned here and one size never fits all.
