How many people have ran these or the 372xp? This is my father in laws saw and its 2 1/2 years old and was still running and cutting. He said it was starting to get a little weak. Now he cuts timber full time and 2 1/2yrs I think is pretty darn good. He has had several through the years and this one is actually a redmax version. I have the jonsered my self and cant say enough good about it. Considering the hours and abuse this thing has been through, I'm suprised it still runs.
