I have yet to find my #1 wishlist item--Kuririn, 
from DBZ, dressed as Piccolo from movie 10.  I've 
all but given up hope for it, but keep it on my 
wishlist just in case one ever pops up.  I've 
been looking for this cel for nearly 3 years now, 
and have yet to even see one in a gallery; you 
can imagine how frustrating that can be.

But I've found a lot of other stuff on my 
wishlist, and have gotten to the point where I'm 
willing to quit collecting if I get just 2 more 
cels.  I think the likelihood of your actually 
getting what you want depends on your tastes and 
your persistance.  In my case, I doubt there are 
more than 30 seconds of footage of Kuririn in 
that outfit, and most of those are of him passed 
out without the cape and turban.  If yours is 
just "A nice cel of xx," then you might be a 
little better off.
