The Stihl is a good chain saw - lots of power - but all the ones I've used/seen shake like a dog shittin' bones... I hate the vibration and they install all kinds of rubber mounts to absorb some of it. Then the rubber mounts go bad and the thing acts like it's going to fall apart. I needed a couple of parts to repair one for a guy one time, and called the factory - response was "If it's more than 10 years old, throw it away - we have no paperwork, parts, or tech support for the old stuff." From that time one - I would never recommend someone to buy from them. I personally have a Poulan 18" and have had no problems with it (and I cut a *lot* of firewood, about 13 cords/year or more). Hope this helps. Ken.
