Yeah, I love my dougas, gengas etc. All of them 
are individual pieces of lovely artwork to me & I 
put it into consideration when i buy a cel. If it 
has a sketch, I'll pay more. If it has more than 
1 piece of sketch, I'll pay even more:)
It's either a matching BG or a douga...or both!
I might compromise if I really like the cel 
though but if either one of this is missing, the 
cel doesn't feel tt complete to me.
So it's unfortunate tt cels & sketches are 
seperated by some cel dealers juz so they can 
make more $$ :(
