There was just one for auction on yahoo Japan a 
week or so ago but I don't know what it went 
for.  You could have a fan cel done in the mean 
time while you look.  Or better yet get her 
involved in the search - thats a good way to 
drag 'em into the hobby!  You can also e-mail 
dealers directly with your request. Sometimes 
there able to locate things.
Good luck - I'll keep my eyes open for you!
