Have you watched the videos on the Timberline site? It is a very precise tool and will get a nice result. I just think the setup time for different chains all the time would really bog you down. If you had all 3/8 .050 on every saw you own, then it would be easier to justify. I would look for a bar mount file guide (Granberg File-N-Joint) way cheaper than an FG2. If you come to the conclusion filing sucks, then look for a grinder. If you conclude that filing is the only way to get the edge you seek, then hunt down a FG2 at a price you can afford. If your buddies are bringing you rocked chains, get a grinder. Filing is for lesser damaged chains. Hope this helps some, it will boil down to personal taste in the end.
