I don't have any fry right now, but did just manage to get the last three pair from a supplier last week. I'll be posting a for sale thread once I get fry from them, so they will be available in the US again. In the mean time, I can only wish you luck in your search. It took me almost six months to find them, and just happened to get lucky in asking the right person.
Impossible only means that somebody hasn't done it correctly yet.
