I have a Bernina 230PE and a small portable Janome, I call it baby. I got the a four piece box of accessories at Sears so I could get the walking foot for the Janome. In the box is a screw seam guide that works great on my Bernina. I love it, will use it even with the #57 foot just to keep my fabric a little straighter while feeding through. Included in the box-walking foot, seam guide, 1/4" foot for Sears/Janome machines and a free motion foot. It was $24.99 for the set. By the way, the seam guide won't work on the Janome, there isn't a screw hole to attach.
