I'm still dreaming of a walking foot with SITD. For now, I have a generic from Joanns. Full price was $15 and I used my 40% off coupon on it. It works just fine on my Brother. I had a dealer tell me the feet aren't interchangeable between brands. Not true. You just have to know if you have a low shank (most likely), high shank, or slant. Check out Amazon for feet. My darning foot was less than $10 on Amazon.
