I tried out both in Paducah. I really liked them. I have a Bernina 440 QE with the stitch regulator and don't particularly like it. I found that it got in the way of my stitching. However, I tried the HQ stitch regulator and really liked it. It works like a wireless mouse. The really neat thing is there is a magnet that fits on the top of the regulator mouse which anchors the quilt. If you rest your hand on it while stitching it gives you some more control. I am starting my HQ savings account and hope to get it.
