Hello,
I hope that it is not too late to add my two cents about chain saws.
I am a Captain with the California Department of Forestry and Fire Protection and I have used both Husky and Sthil saws extensively. I worked several years in a CDF Conservation Camp see link:

In a CDF camp we have used both Husky and Sthil saws for use on wildland fires. On average, a saw will see 50-100 hours of work on fires each month operated by inmate firefighters during the fire season and about the same in the winter for fire prevention projects. My camp has 6 crews with four saws for each crew and about 10 saws in reserve. As can be imagined, these saws see some of the most severe use by somewhat less than caring operators. Generally, a saw lasts about two fire seasons before being retired to the scrap bin.
In my experience, both Sthil and Husky are very good saws. I have used mostly Husky 268, 372, Sthil 044, and Sthil 046 Magnum saws. My favorite is the Sthil 046 Magnum because it has one of the best power to weight ratios of any saw on the market. The only thing I have ever found that I don't like about any of these saws is that Husky uses the handle for the gas tank and if it is rested in some coals the handle melts and the saw erupts in fire. Don't try this at home!
If somebody is looking at a saw to purchase, stick to Husky or Sthil professional series and avoid any saw designed for the weekend warrior. The cheap saws are garbage and will be a waste of money and frustrating to use. In contrast, a professional saw will last a lifetime for the average homeowner.
I hope this is helpful, check out the cool photo:
