After being in the tree business for a few years I have accumalated several saws. They are all stihls. The high end huskys are good saws albeit very loud no dealer support in most areas. The Stihls on the other hand have a great dealer network, and if the dealer doesn't do you right just contact the distributor and they will make it right. Keep in mind that when you buy a Stihl that if it has a orange handle it is a homeowner model made to compete against most retail outlet stores. If it has a white handle it is a professional model. For general limbing and small felling the 361 is nice it has the anti vibration handle. They don't make the 038 any longer so the next best thing IMHO is the 440 which replaced the 044. It will run a 24" bar fine. If you are going to cut alot of big wood for fire wood go with the bigger saw. It will make life much easier and your job will get done alot faster.
BTW chainsaw chaps are your best friend. An employee griped all the time because i make them wear chaps while cutting on the ground. One day while doing storm work he was running a 650 Magnum with a 36" bar. I heard him start yelling and screaming like a snake had just got him. He emerged from the tree with a ghostly look and some mangle chaps, but not a scratch other wise. Before you say he didn't know what he was doing he has been cutting for 3 or 4 years. Most people will tell you that they know how to use a chainsaw and have never had one kickback, but it only takes one time to ruin your life permanetly.
