Actually, there are only four cels right now 
that I can think of that would I simply quite 
collecting after I found them, so I'll throw 
them all in here...and two of them are American, 
seeing as how I've found 75% of my ultimate 
anime wishlist:

Cel 1:  Seiryuu seishi Soi from Fushigi Yuugi 
with her hair down.  I would sell off half of my 
collection, would even consider giving up 
Suboshi for her, especially for any pan cel of 
her with it down.

Cel 2:  Rodimus Prime/Hot Rod from 
Transformers.  I don't care where it's from, I 
don't care what the shot looks like, but I want 
him.  Even more than Magnus.

Cel 3:  Ultra Magnus from Transformers: The Movie

The three images you see below are the specific 
screenshots that would just get me in all a 
tizzy, but I would basically take anything.
