I piece with a Pfaff 1471 (about 20 years old or so and Pfaff's first computerized machine) I love it!!!!! It even has built in walking foot, needle down and programmable stitches!
I quilt with a Pfaff Grand Quilter. It only has a straight stitch and a 9" throat which is nice for quilting. I've had it a few years. Dani
