I have a Bernina 1260, purchased 16 years ago, and use a 1/4" foot rather than depend on the line on the machine bed. The 1/4" foot is #37 and a 1/4" foot with a barrier on the right side is #57. Both work wonderfully as long as I do my job of following the edge accurately. As patchsamkin said "Love it and will sew with it until it no longer works."
