I bought the 1/4" foot, too. I'm not sure about that one. First I liked it, now I like a metal guide screwed to the machine better. Also the SITD foot. Love that one. I wouldn't SITD without it. I haven't needed a walking foot - Annie doesn't shift the fabric like the Elna. A new tire for the bobbin winder (Annie's was dry) and a screw for the thread guide someone on the board gifted me with. The regular Singer screw wouldn't fit. I have purchased a tension spring as Annie's seems a little springy, but so far haven't needed to install it, but for $2.95, I'm covered. I could get at sewclassic for less than a $1, but there is a minimum purchase and a shipping fee that's much more than $2.
Look at the home page at the $600 original penguin walking foot for the featherweight. The first time I saw it, I had to read it twice.
