I am getting my first real saw to replace a wild thing that was not very wild. I am looking for a saw that can run a 18" to 20" bar and is good for all around use. I am taking over the wood cutting duties for the family and need a saw that will last. I am thinking on a Stihl MS310 of a Husqvarna 460. Which would be better? Is there a better saw for my needs? I am only looking to spend around $400 to $450 MAX. Thanks.
