I was wondering if you guys could recommend a chain sharpener for me. Between me and my brother we cut about 35 cords a year. I want something that wil do the job without alot of messing around. I just see there are 100 dollar sharpener and then there is 500 dollar sharpeners. I just want a quality tool that should last a long time. I just don't know what is worth the money and what isn't .
