You need to check to make sure the new interchangeable one is compatible. I just got it for my Ruby; it comes with the zig zag and straight foot and you can buy the 1/4 in and others separately. I paid 128 at my LQS but recently saw it on Amazan.com for 97 (I think, it was under 100) It fits most Vikings with a few exceptions. It's great because it goes in reverse and you can do zigzag and more with it.
