Want to Buy WTB: 400iso DX coded reloadable cassettes

Looking for a half dozen or so cassettes that are coded for 400 ISO. A couple 800's or 1600's would be fantastic too, but I'd be happy if I could find some 400s. I've read a bunch of the hack instructions and might try it, but I'd rather find some of the real deal canisters.

Thanks for looking!

Not sure if you're looking for new or used, but Ultrafine sells two versions. The former are available in 10, 25, and 100 packs:
