If you plan on sharpening chains I suggest you spend another $25-50 once you get your machine. What should you spend it on? INFORMATION Find the best sharpener in your area and give him or her the money to spend a 1/2 hour watching them sharpen and asking questions about wheels, chains and angles. Their experience and info will be far more valuable than $25 and save you a lot of headaches down the road. The ease of sharpening you see in person and videos is accomplished after hours of practice and a knowledge of how a chain works, types of chains (aggressive, safety, skip, square, raker depth) types of wheels, wheel maintainance etc. As Bert said, don’t be cheap. If I was going to get another one, I would go with Oregon.
