I've owned and used a good number of saws, including more expensive ones. I have nothing bad to say about this saw... It cuts good, has very low vibration, starts easy, was a bargain($200 sale price) and hopefully will last forever with its chrome lined cylinder. I don't know about being a "professional" saw but definitely upper end for home user, occasional user. Made cutting down and cleaning up my willow tree with a 3 foot diameter very very easy.
