Hmmm.
I once watched someguy who won silent 
auction for a slayer (zelgadis in costume?) cel 
which was about 3,000 yen, made X00( 3or 4) 
bucks at ebya.
I envied him so much just because I bid 2,000 
yen.  
I lived in japan when I was a kid, but now live 
in the states. I think American cel collector and 
Japanese cel collector have a little bit different 
taste. Personaly, I couldn't order everything at 
animanga sale, becasue I spent all my budget 
in anime-taro sale and they were new cels so 
only 10 % off. What made me relieve is I am 
99% sure that what I wanted to pick up will 
survive till next sale. Those cels survived this 
animanga sale and what I picked this time 
survived from last animag sale.
