I have a MS260 pro that I have used for years but I have to pass on many finds or call in a someone with a bigger saw and of course split the wood with them. I am willing to spend around 500 for a used stihl and I am thinking of something like a 440 or 660. I think it would be used very little because I like the light weight of the 260. Would an older model meet my needs just as well? Any recommendations?
