I saw that cel also.  I thought it wsa nice, but 
that price is crazy.  I have mentioned before 
that I think that cels are only going for these 
crazy amounts because people here in America have 
seen the episodes on video.  I saw that episode 
about 4 years ago in Japanese.  I might have paid 
$50 for the cel at that time, and I still do not 
think that I would pay more than that for it 
now.  I will admit though. Because of the high 
prices, I plan to purchase inexpensive cels, and 
then sell them on ebay, as soon as the episode 
hits the cartoon network.

I just hope the cels that I plan to sell can go 
for such crazy amounts.
