Pros:Inexpensive saw, not too heavy.
Cons:Not the most reliable, poor chain adjustment design.
The Bottom Line: Buy this if you don't rely on it every day and just need a step better than a "yard cleanup" saw.
This is the 46cc 20" chainsaw from Poulan Pro. I bought it used via Ebay from a small-engine repair shop. It comes with a tool-less chain tensioning system, automatic chain oiler, anti-kick chain brake, and has spring mounted handles to cut down on vibration getting to your hands.

First - The tool-less chain adjustment is prone to stripping the plastic thumbwheel, which then leaves you trying to adjust it by grabbing the tiny end of a shaft with a pair of needle-nose pliers and twisting. Not very robust or easy to use. The nut that holds the bar in place also tends to loosen during use, causing the chain to lose tension and jump out of the bar
Second - 20" of bar is nice for cutting down a tree, but 46ccs is a bit on the small side for that much chain. It's useable, but you have to be careful about putting too much pressure on it or it'll stall the chain.
Third - The anti-vibration mounts are somewhat nice, in that your hands aren't 'buzzing' when you get done. It does make it feel a bit mushy when you're pushing down into the cut, though.
Finally - I don't know how common this problem is, but one of the main crankshaft bearings blew apart while in use. I just finished repairing it and it does work as well as ever now. Parts are inexpensive and not hard to get.
Overall - this is NOT a professional quality tool. If you cut a lot of firewood, I'd highly recommend a better saw. For the weekend-warriors who need to do some occasional yardwork and even less frequent tree-cutting, this is an adequate saw for the price.
