I own a Stihl 290 with a 20" bar. How do the Dolmar 5100's stack up against this saw? I like the lighter weight of the Dolmar, but is it as reliable as the Stihl? I ran a Husky 450 this weekend and it was a great saw, light and really seemed to cut! Not sure if I should look into the Dolmar line of saws? Do they last?
