I have both the #37 and #57 foot. I love my #57 foot. It is wonderful when making Drunkard's Path blocks. I would suggest you sign up for Bernina's online magazine Through the Needle,every issue they have coupons for their presser feet. A coupon for a different presser foot every magazine. It's free, too! The #57 foot is great when piecing, but the straight stitch plate is also great for piecing. If you buy a straight stitch, remember you can't use a zigzag stitch.
