Domestic machines don't go fast enough for a stitch regulator to be efficient. You can out-run it too easily. A laser stitch regulator (like the BSR) is less efficient than one that records an actual X and Y movement (like on a longarm). I vote for getting an Avante with a stitch regulator. The Sweet 16 regulator is a bulky thing that attaches to the quilt, and isn't very effective.
