Hi guys - I've been wanting a grinder for a while - I hand sharpen, and can sharpen well, but after about 10 sharpenings, I think I could stand with truing the angle again. The Oregon sharpeners seem real nice, but pricey. I was looking at this http://www.northerntool.com/shop/tools/product_200327449_200327449. Seems to get pretty good reviews. I'm not adverse to saving for the Oregon if it is far superior - particularly since I'm thinking of offering a chain sharpening service. Any thought appreciated! Cheers!
