I get them from my local welding supply if I can, and its not on a Saturday. They carry Pearl, which have some of the best abrasive products. Also I will, if its on a Saturday, pick up some decent product from my hardware store. They sell dewalt but also sell several other brands, including one called "Ivy" which is a hardware brand I think, but fairly decent in a pinch, and a great price. I also will pick up some at fastenal on sale. They keep a rather large supply too. Not the best regular price, but if it is on sale, I'll pick it up. Their blackstone brand isn't bad, but it isn't great either.
