Totally agreed!

"Price in this hobby is so
incredibly subjective to begin with, your feeling
for the cel seems to be the most important part 
to me.

If the financial aspect of the situation ruins
your enjoyment of the cel, it might be worth
backing out of the deal despite possible
consequences, because there's nothing worse than
$700 worth of acetate in your binder that you
can't bring yourself to look at without feelings
of resentment." - Evil Minion

Couldn't agree more! ^_^ Personally I think the 
one you're buying sounds more appealing, a KEY 
with a matching copy background , when displaying 
it will look magnificent and the way it should! 
There's nothing better than that. For me, the 
sketch is a bonus.
