MM well from most of the YYH auctions I've seen 
on YJ, I think they're mostly Japanese bidders. 
I don't think Cartoon Network has taken a BIG 
effect yet on American cel collectors, but who 
knows...I started collecting not too long ago, 
but I collected before YYH was aired on Cartoon 
Network. I think one of the reasons for such 
high prices in the cels is because before all 
this, there weren't too much YYH auctions on YJ, 
so maybe b/c of 1 nice auction (where everybody 
bids and bids), then sellers starte thought that 
if maybe that 1 auction could go high, then 
theirs could also so they decided to put up more 
YYH cels. That might be one of the reasons why 
there are so many cels on YYH auctions~

PS- Just curious, who is MikaNoNamida? He/she 
won so many YYH auctions that I tried to bid 
for ;_; I heard the person is residing in the 
U.S., and I was just wondering if he/she is a 
postee here.
