I've heard these go for about $300-400 isn't that nuts? I've also heard you can use a regular low shank walking foot or darning foot for the featherweight or the 201 which is what i plan to use. It would be cool to have this one since it's black and would match the machine but not for that price! It ended but did it sell? wow...
ETA: I just looked and it did sell at $385. must be a great foot... or someone just wanted all the authentic parts..
