After processeing about 20 cords of logs over the past year, including felling some 24" diameter spruce on my property with my ms180 I am now at least three years ahead. I was just out taking down a snag thinking to myself I wish I had a little bigger saw, when my neighbor comes over and offeres up his ms250c, said after seeing all the work I've done, that I might want a back-up saw. Said he just picked up a new saw and wondered if I wanted to buy his old one. He bought it new in 2003, had the receipt for the 10 hour service in 2008, it has the original chain with a ton of life still in it, I doubt it even has 10 hours on it! Comes with a case! I'm standing there looking at it, thinking man if I could get it for $150 that would be a great deal, when he says " how about $150, that's about half what I paid for it". Only thing is, it's got a 16" bar that I will definitely switch to 18". Guess which saw will be the "back-up saw"?
