Yeah.. wouldn't make sense for me to own either. I bought an Oregon chain sharpener and seemed to spend more time changing the set up to accommodate the various pitches and profiles of chains that I have than I did sharpening. I stopped using it and went back to hand filing. I use a basic Stihl file holder and basic Husky depth gauge and get excellent results quickly... I don't worry about every tooth being exactly the same length either as they work independently... I haven't had any vibration problems doing that so will continue to do so. That gives me longer chain life too as I'm not turning lots of useable tooth into swarf while making the teeth all the same length.I was wondering if it burned cutters myself. Also, can it be set up to do all three chain configurations? FC, SS and FS?
If the machine actually works well and dose a good job. I could see owning one if I were to run a big saw shop down south and folks were constantly bringing in chains to be freshed up. Other than that. I'll pass, its just not practical enough for my needs and probably a pretty penny.
