Well... I got this Video Girl Ai cel for free:

 by accident when I bought this one for $40:

I'm also getting a FRAMED cel of Goliath holding 
Demona from Gargoyles for $250 considering the 
$250 to $500 dollar range for an UNFRAMED 
Gargoyles cel, that's a good deal. *bounce*

Alot of my Youta (VGA), She-Ra and Slayers cels I 
got for about $30 to $50 a peice, which for me was 
a deal... :)

I got my Lantis/Fuu for $12

and considering my Last Unicorn cels weren't like 
HUNDREDS of dollars... (gah! some of them sell for 
WAY too much!) I'm happy with the deal I got on 
those too!
