Thanks for the heads up! My DH and I went to Harbor Freight yesterday - they had about 10 packs of the blades hanging up and I bought 5 - haven't tried them yet. I also found the micro vacuum attachment pack so I can really clean out my machines! (learned about it from another thread on this most excllent board!) DH thought it was funny I wanted to go to HF, he got a kick out of it. ;)
