It's just a matter of how you look at it. Once 
that person owns it, it's theirs to do with as 
they please, and there really is no right or 
wrong. I can sympathise with the seller, I really 
don't care much for my dougas, either. Mine sit 
off to the side in a plastic bag unappreciated. 
It's the cel that really shines. I've never 
understood the desire to collect dougas. I know 
it's the animator's original drawing, but usually 
they have at least a bit of paint damage,(which 
turns me off) and it doesn't stand out like a cel 
does. I think cels are more special because 
that's what actually went under the camera and 
you can see on your tapes and dvds.
