Ah, I think I know which cel you're talking about 
(Guts vs. Griffith in the snow, aeriel view) and 
it's at Mangaya. Unfortunately their site is 
currently down at the moment, so I couldn't 
access it to recheck. I'm pretty sure it's them, 
though. They only had, maybe, three or four cels 
in total, however.

Well, I dunno if I agree with the "more supply, 
less demand" theory. More supply, definitely, but 
I don't meet too many people (cel-related or 
otherwise) who have seen the series to even like 
it. I'm not seeing a big demand, and I think that 
may be the problem here. If more people DID want 
cels from "Berkserk" I think they'd be easier to 
find, maybe more plentiful as more dealers would 
be working harder to specifically find "Berserk" 
cels, you know what I mean? 

Either way, I'm resigned to the fact that a great 
quality cel will cost upwards of $400. But hey, 
for the pan cel of Griffith from Casca's 
flashback, explaining to her why he [you know - 
if you don't know, watch the show! ^_~] for 
money, naked in the brook with his hair draped 
over one eye (the other blue orb showing in the 
crazy berserk way as only Griffith can achieve^^) 
and hugging himself, clawing his own arms bloody 
*babble, babble* ... Yeah, I'd be willing to 
shell out that much! *^_^*

It's such a shame cels are so rare because 
there's visually a lot of great shots to be had - 
there's a lot of oversized and pan moments, some 
beautiful character images, great medieval-style  
backgrounds, and a heck of a lot of harmony cels! 
Such a damn shame... =P

If you're searching for hard-to-find cels, all I 
can think of to suggest is: ask people, inquire 
around to dealers and sellers. Sometimes you'll 
hear good news. Mandarake seems to find the most 
at good to decent quality, so maybe they can help 
you look?

One *really* long-shot, too, is run an image 
search through Google. I know that sounds odd, 
but that's exactly how I found my two big cels of 
Nova Universe from "Gall Force". It pulls up the 
picture (if you've seen enough cel scans to 
aquire "an eye", you can usually tell if it's a 
cel image) and gives you the url of the site it's 
on. I probably would never have known that Anime 
Cellar had those beauties unless I did that. It 
was unusual, and I got lucky! ^_^

I hope I helped a little, and best of luck to you!

(oddly, I'd also like one of the numerous cels of 
Griffith's gorgeous eyes - there's a lot of shots 
that pan across his eyes all the way that would 
be so enchanting to have! *sigh*)
