I've had some luck with having a wishlist up 
actually. One person saw I was looking for a 
specific character, and offered to sell me 
theirs :D I have also had dealers email me 
because of cels on my wishlist.

(btw, the wishlist i'm talking about is at my 
rubberslug site).

I actually try to keep a wishlist - to *control* 
myself. But it has yet to work. ^^;;; (i have a 
tendancy to make my requests very *general*)
