Gee I'm surprsed that your not quilting with your Designer.
I have a Husqvarna SE and can't live without it for the embroidery and quilting. Since viking is the only manufacturer with the Sensor Foot that lifts on it's own for pivots...how could you not use it for quilting? I know I wouldn't buy anything but a Viking with a Sensor foot once you have it you can't live without it...
