Part of it's that, yes. Part of it's the current 
cel market, too, for the last several months. A 
lot of would-be cel collectors find their jobs a 
little uncertain, their nest egg a little small, 
need to save up for tuition, need to save up for 
the next convention... and so there's less money 
to jump in and compete with other bidders. You 
also have lots of people trying to sell cels, and 
relatively few are buying--- so prices tend to 
often drop, where people are willing to let a 
$150 cel go for $100 if they want the money 
*now*. And part of it is that the particular 
seller I think you're referring to has kind of 
glutted the market recently (ie, at least the 
last ten months), and spoiled us... although I'm 
very happy that he has done so, as my collection 
is much larger for it. ^_^  But it's had the side-
effect of making us grasshopper-types come to the 
realization that, with so much coming past, we 
can sit back on our haunches and wait for a 
*good* one, as opposed to snatching up anything. 
So instead of fifty people all fighting for a 
shot of the back of someone's head, the 
competition goes down, and decent shots end up 
going for reasonable prices, instead of, say, the 
triple-digits they would've sold for this time 
last year. ^_^

But those are probably the biggest reasons. ^_^
