Large fowl or bantam?
If you want large fowl, I know Jerry Foley has the best ones you can find right now, but they are pricey. Everyone selling them says theirs are Foley line, but be prepared that they are not.
If you want bantams, I might know someone in Texas with them.
You can find them for sale on here (chicks and hatching eggs), but I would ask to see picture of the actual birds being used as breeding stock so you know what you are getting. The lacing can be all over the place on them. Look for ones that have nice dark red too, not orange.
