I order my belts from trugrit.com. My most used belts are the Norton Norzon (60-120 grit), great lasting belts and worth the money. I also use Norton Blaze (ceramic), but at over $5 a piece for a 1x42, I use it sparingly. Another brand I like is 3M; I tried some klingspor belts once, but they threw this red dust all over and I didn't like the way it cut, so mostly norton and 3m for me.
