I have looked into some of the cel's and they are 
very expensive.  In fact, only Ghibi seems to be 
more...

A good shot of Deedlit from the OAV may run you 
anywhere from $500-$1000+ depending on the seller.

But the TV you can find cel's for cheap.  Like 
some of the Chibi-characters for dirt cheap 
(check Yahoo Japan)...

I want a good Deedlit OAV myself, but not for 
that kind of money. (So if anyone reading this 
has one and feels like just giving it away, let 
me know!)
