I agree with the others, spend a little more and get a good saw. I have a Sears (polan) 3.5ci 18in bar. in. The saw always starts and runs fine and I probibly have 40hrs or more on it. But I hate using it, my hands go numb after cutting a tree up, even with gloves on. It doesn't have the anti-vibe, some of the polan pros have the anti-vibe. I also can't cut a large tree without two gas and one bar oil refills. The better brand saws will have bigger tanks allowing you to work longer. In hardwoods it seems underpowered, you really have to let it run high rpms, it has no lugging power like some of the Stil's, McColuch's, or Huskies I've used. On my .325 chain I've ground down the limiting teeth some (raker?) so it cuts much better than it did out of the box. I also have one chain I sharpened every second or third tooth flat, instead of angled. It cuts through pine trees in no time, instead of all small chips you get large amount of 1-2" shavings comming off the saw. This type of tooth style as I understand it is better for ripping but it works well in cross cutting pine, but will bogg down the saw in a larger hard woods.
