I own the tiptronic 2020. My daughter's husband was stationed in Germany and Naomi brought home a pfaff for me. (I paid of course!) It is a wonderful machine. One can't praise it enough! In fact I can't sew without the dual feed anymore! I have a Bernina with the stitch regulator. I love using it for quilting but I almost always use the pfaff for my piecing!! It's my rule :!:
