I dunno, if that were a fancel, it's pretty 
beyond my ability, and it would be using some 
pretty high tech goodies (like an aibrush) that 
cost enough for me to not even consider getting 
them just to play with them.  

I've seen plenty of clearly marked (and failry 
poorly done) fancels of dragonball tv go for 
disturbingly high prices, and some very nice 
reproductions (one of a AMG hanken comes to mind) 
of hankens go for very high amounts on ebay, and 
from what I hear, yahoo! japan too.  While it's 
not as good as the hanken repro, but certainly 
nicer than any dragonball repro I've seen, it 
would still probably fetch a pretty high price.  
Maybe not 200+, but I wouldn't be too surprised 
about $100 at least.  

...and let's not forget how much 'official' hand 
painted reproduction and 'limited edition' hand 
painted cels go for.  Not everyone is in it for 
owning a piece of the production, some people are 
just in it for the pretty picture.
