Gainax is only producing them when someone order 
them and that takes a couple of months. I have one 
more of Rei that I am keeping for myself and I 
should receive another but I don't remember which 
one it was exactly : I ordered them in May I 
think... :)

But, yes, I guess that if you are interested by a 
specific cel and can't ordered it yourself, I can 
do the middleman...

Cheers,
