I have never owned a chainsaw, heck I have never used one. I want a stihl brand because I own some other stihl products and have been happy with them. I need something that I can trim no bigger than 8" branches with and occasionally cut down a smaller size tree for a customer. This saw will be used less than once a month. I was thinking a ms 210 their smallest saw would do what I need. It has a 16" bar. Am I going to want something with more power....or for the occasional use that I will use it for is this suffecient?
