I have the 820 and love it. I think BellaBoo is talking about the 830. The 820 doesn't do the embroidery, and costs well under $10,000. I don't have any problems with mine...absolutely no vibration at all. This is my dream machine and to me worth every penny we spent on it! I went from sewing and NEVER completing a project because my "other" machine was frustrating to sewing every day! In case anyone is wondering, I do NOT regret going with the 820 instead of the 830 either...but I am not inot embroidery either :)
