I got the Janome 1600 DBX over the summer to use on a quilting frame. I have yet to fully master the frame and find myself liking the machine for regular sewing and quilting off frame. It is a fast machine and is only a straight stitch. It has auto thread cutter and knee bar. Someone correct me if I am wrong, but it is supposedly very similar to the viking Mega stitch and Pfaff grand quilter.The machine is very heavy and I think it is a sturdy one. So far I am happy with it. I have to get a walking foot for it since all purpose ones don't fit. I got the free motion foot which is fun to use.
