Shucks.. ;.; I was really hoping this would be 
news on some hot Yann-Nick action..

...err... Kidding.  Of course. ^.~;;;  *cough*

In any case, I would have to agree with the 
earlier posters.  The cost of the cel is only 
one piece of the whole -- the dealers often have 
to pay to either have someone out there picking 
cels up for them, or for transportation in and 
out of Japan if they're not a native.  A lot of 
costs come into it -- transportation to/from 
Japan, transportation within Japan from shop to 
shop, room & board, and various other overhead 
costs.  Besides which, oftentimes dealers end up 
with things they -think- will sell, but may 
not.  That means monetary investments into these 
cels which don't turn around.  If a dealer has a 
thousand dollars represented by non-selling 
cels, they have to recoup that money somehow if 
they're going to continue to acquire more cels 
to sell, or eventually they'll be stuck without 
any money with which to add new products, and 
then -- well, as was mentioned in an earlier 
thread, that's when they have a big sale, take a 
bit of a loss, but get some money out of those 
cels.
And if they make a profit, that just means that 
they'll keep seeking out these cels and making 
them available to those of us who can't afford 
the time and money required for a trip to Japan 
to get these cels at the source.  And that's a 
price-hike that makes it worthwhile.
