I cann't see buying cels from shows I hate or 
totally disinterested in, I have had plenty of 
ops in the past to buy stuff like DBZ cels and 
probably be able to resell them for profit but I 
passed as just had no urge to own something from 
that show.  

Now I have occassionally bought a cel from a show 
I haven't seen, just because something about the 
cel appeals to me.  But if I then see the show 
and don't care for it, I may eventually weed that 
cel out - that is what happened to my Youko 
Kurama as once I had seen the show and it didn't 
float my boat I was willing to let it go.

As long as I consider a cel very pretty its fair 
game, unless its from a few shows that are a 
total turnoff for me.
