The main advantage to using the non-Dremel (Large wheel with jig) type
of power sharpener (whether from Oregon or from HF) is that the jig
helps to even out tooth length - which helps things to cut straight when
you've munged 3-4 teeth on one side by clipping a rock or nail. It's
what the pro saw shop here uses to sharpen chains.

If you're patient, there's no reason you could not do the same with a
file and gauge of some sort. The jig/grinder setup makes it easier and
faster.

In the field, I use a file with every tank of gas, or sooner if it seems
to be needed. I swap chains if one gets munged too badly.

Power sharpening also has an advantage with carbide chains and diamond
sharpeners, but that's a whole 'nother level of spending.
