I agree, for bulk purchasing of rotary blades, ebay is the way to go. I also bought the harbor freight. I only bought 2 packs because I didn't want a lot of them if they didn't work. My first blade was nicked so badly you could see it with the naked eye. the rest of them seem OK. Moral, use new if you have them, buy at the best price you can find, sharpen when you have one going bad or can't get out to buy new ones.
