A pro saw is a waste of money if you're not going into the firewood or logging business. I cut 4 cords a year for firewood. My ms290 farm boss lasted through 8 years of that before I sold it to my brother 5 years ago. He's been cutting 15 cords a year with it since and it's still going strong. I sold the farm boss and bought a Husqvarna 445 because that damn 13 lb. beast was killing my back. At 10 lbs. the little Husky 445 has proven plenty powerful and much easier on my arthritic back. After 5 years and approx. 20 cords of assorted oak, cherry, hard maple and ash it's still running and cutting like new.
Guessing you don't have much pro saw experience.
You wouldn't have to wear out a saw to determine if it's a homeowner model,
longevity is but one advantage.
