I have a pq1500s 9" and I have some westlee and other brands of rulers. But the one I use the most is the one I got off the Judi Madsen website. IT is a short straight ruler with an angled handle. It seems to be the right length for my machine work and the angled handle makes it easy to use in any direction. It is my go to ruler and it is inexpensive and you can use it with any ruler foot
