For anyone interested, Harbor Freight catalog sales has their chain
sharpener on sale for $59.95. I have had one for a couple years and am
happy with it. It's not a heavy duty pro model, but it doesn't cost
hundreds of dollars either. I still sharpen with a file most of time but
this thing is worth its weight in gold when I hit rocks or nails and
really do a number on the chain.
