Well, the posting last week, and much thinking, I did buy the Janome 6600! Everything is still in boxes, as I am making myself repaint the sewing room before I set it up. I still don;t know what the little opening on the throat plate is. My dealer says it may be for additional equipment. I'm excited, and will keep you posted on the performance. Oh yes, I kept my Brother machine to take to classes..More to came Sherry McD
