You can usually pick up a Poulin Pro with a case and extra chain, etc. for around $200, if you're on a budget. They're made by Husquy so the motor is solid. The "Pro" has anti-vibrate, which the normal model doesn't. The bummer about these are it's hard to find parts when things break, so if your pull-cord rewind breaks (for example) you might not be able to replace it. What causes your pull cord to break, is that the tuning pegs don't have standard screw heads, so basically you can't tune it. So after a year or so it gets harder and harder to start, since you can't make a simple adjustment, you just have to pull that cord 20 $*#@ing times to get it going, which wears out the rewind and eventually breaks, and you can't find a new one because the replacement part that is supposed to fit these things doesn't, so basically you have a saw that doesn't work, even though it's a Husquy motor and you just bought a brand new bar and chain (*deep breathes, deep breathes*).
A way to overcome that tuning obstacle is take off the carburetor, put the saw in a vice and take a hacksaw to the tuning pegs so you can adjust them with a screwdriver. I've done it because I couldn't afford a Stihl and it's worked for me so far. But Stihl and Husquies are worth every penny if you can swing it.
