I've been running Stihl's for 20+ years. Usually find used ones to buy but used prices are within $150- 200 of a new one and those that aren't are beat to death. Currently running a 290, 310 and an 041(only when I have to because it beats the hell out of me). I'm looking at a new 391 with a 20" bar because I'm tired of working on the old ones to keep them running. The 391 appears to be Chinese made, therefore I'm concerned about reliability. I saw good reviews on it, and some stinkers. I don't fell much anymore, but I do cut 30-40 cords of hardwood yearly. Any info would be appreciated.
