Two saws to stay away from Stihl MS 170 hard to start when hot ! Husqvarna 439 grossly underpowered with a 16" bar !
Of course it depends on what you're cutting. For real small stuff (like 8" or less) the cs3510 is a pretty good saw. If you want to cut much 10"-14" stuff the cs400 or the new cs4010 are pretty good options, but both those saws get really slow in bigger stuff. In my opinion and experience echo is the best option for small lower priced saws. I've had a husky 435 and a couple 440's as well as a Stihl ms180, and the echoes have been more reliable hands down.
Stihl 201c. The long handle version 35cc or 261c 50cc I guess it depends on your definition of light.
I've had a 352 for years, great little saw. The 3510 is the new version. I think you can still buy the 352 for now.
What do you consider light weight? Is there a price range you wany to stay below? I have a few recommendations but they are all over the map on cost.
My most used saw. It rips but a 16" would be a bit much. I run a 12" but a 14" would be doable for sure.
I was in a water rescue accident while working at our fire district, injured my back, shoulders and neck. I have a Husqvarna 61 and a 450 Rancher that are great for the big stuff, but kill me when I'm cutting smaller limbs. So I guess I'm looking for a saw that I can use around the house and cut up limbs and smaller logs maybe 10 to 12" max. Could be a 14" bar. Price around $300.00.
I know all to well about the light weight needs. 4 neck and a lower back surgery has me really limited. My biggest saw is 43cc and 12.8 pounds fully gassed and ready. The smaller Echo saws will probably be the best fit for your price. I like Echo as well as any maker. My other recommendations are $500-$800
