Thank you all for the info on this topic. I am vacationing in Portland, Oregon and read of the rotary blades yesterday. Lo and behold, we passed a Harbor Freight store today and I was able to get 19 packages. If I waited until I got home to California, it probably would have been too late. I also found some great little plastic clips that I think might be good for holding my quilt sandwiches together. I can't wait to try out my new loot!
