Apparently these were sold together. I bought only the Janome 1600 P secondhand this last summer. I read the reviews online and was not sure I should buy it. The lady I bought it from said that the Grace Machine Quilter Pro was horrible with the Janome and she sold it to a friend. All the reviews said it was not a good match. Bought the machine and tried and tried to sew on it. Knew the thread thing was broken so I have it in the shop. He ordered the parts and we have waited over 4 weeks now for a small part. He will clean it and then show me how to thread it (not easy) and hopefully it will work for me. The lady I bought it from sewed on it in front of me, but not for an extended length of time. I will hope for the best.
