I've got some extra long shank feet. There's this recycled craft place by me that sells donated craft items and uses the money for Seniors. I can't help buying all the stray feet I find! For $.25 - $1.00 for a set, it's hard for me to resist. The most I paid was $2.50 for a Free Westinghouse back clamp zig zag attachment in a cool art deco plastic case. I've found some pretty cool things there - not always things I need or use, but they look like they need rescuing all dumped in a bin with odd pits and pieces related to sewing.
