Granddad has one of these. It's not even been out of the box.
Stihl chains are really expensive, but great. Stihl comprises of almost all the gas power tools around here. They're the best! I have a 1980s 011AV that was handed down to me when it got replaced as the small saw (still runs as good, if not better than the new ones--and the Chinese carbs used in the MS250 are crap and tend to flood) Cut great, until I hit a rock under the fallen tree I was cutting up. D'Oh!!! And that was a roughly $30 chip breaker chain--definitely, a lot more than an Oregon found at most hardware and farm supply stores. I'm going to try that new electric sharpener/vertical grinder to see if I can't dress out the rock damage (chipped at least a couple of teeth in the chain). And it's not even the oldest Stihl saw I've used. I've used my great-granddad's (currently residing with one of my Granddad's nephews, not me). It's from like the early '70s, and German-made (long before they opened up the Virginia Beach plant). It starts with just a couple of pulls! I've pulled the MS250 as much as 50 times before it would start--my 011AV 4-5 at most. It's just anti-vibration and quick-stop technologies (and auto-oiling chains) didn't exist then.
Even the case hasn't managed to fall apart. This one actually has metal hardware, which the one that goes to my Granddad's 12-year-old MS250 does not. And room for my wrenches, extra chains and spark plug, felling wedges and oil mix.

I have an old '70s Homelite (all metal) that offers just a bit bigger bar than the Stihls we have, as well as an old-school, but small McCulloch I found in a barn. They're rough, and I'm not paying to have them fixed, so guess that's a summer project. There are three that haven't been used since the '90s (including one that got squished by a track loader); so I have a decent stock of parts. These little saws are fairly lightweight, but the heavy amount of plastic parts make them feel really flimsy to me. An MS170 replaced this saw, and it feels (and looks) like the toy saw Stihl sells for little kids to play with. I want something with a probably closer to 18" bar for cutting the larger trees, and new Stihls this size are EXPENSIVE. I've got to contend I've got a buddy of mine who does tree trimming work that wanted firewood (which we use also), and he's helping me out with getting rid of a gigantic (close to 100 foot long, 5 foot diameter) roughly century-old tree that fell on a fence in an upper field a couple of weeks back. He used to run a logging outfit and has some decent-sized Husquvarnas for the job. These 10-12 inch bars are great homeowner saws and have done most jobs around the farm, but I keep finding them too small for what we handle around here.
