I hear you, but not every cel is outrageously high.
You just have to keep your eyes open and wait until 
the "wave" of high bids pass. Yes, there are some cels
that are going for even more than similar cels on ebay,
but there are still quality and affordable cels to be had
on Yahoo. 

There's no such thing as a free lunch, and collecting
cels is an expensive hobby. Even if you have found a "pot
of gold" like a "little known quality dealer" or "a tough
to access Japanese auction", don't expect it to stay a 
secret for long. Supply and demand...them's the brakes.

Rising costs just mean I have to be particularly cautious 
about what I buy. Which means I enjoy the cels I have even
more!
