After some deliberation, I purchased a Brother se400 as my "take along" machine (amazon had a really great deal). While it comes with a few feet, a walking foot is not included. Went to Brother to look for one, and found they have several different styles but without explanation that tells why one is better than the other. I am thinking I might want to use decorative stitches on a quilt as you go project or two. I know the harp isn't huge but hey, the machine only weighs about 11 lbs. Huge improvement over the 40 lb Kenmore that I have been lugging. So, can anyone enlighten me as to the differences in Brother walking feet?
