I think folks are right that you can't go wrong with Stihl, but if you are a homeowner taking down the occasional tree (18" diameter or less), I don't think you need to spend the money on a professional-grade chainsaw. I have an old Craftsman 18" that I "inherited" from the previous homeowner, and it has served me well for over 5 years now - starts first time everytime. I'm pretty rough on it, but keep it properly lubed and replace the chain occasionally. I've used it to cut down ~20 trees/bushes, countless branches and even many treated 6x8 timbers.
