Well, as a collector, I value my cels for both 
their beauty and their value. So, prices going up 
is a good thing. That means cels from this series 
is worth collecting for their value. They won't 
go complete worthless in the future. Of course 
this is speaking only value wise. 

Majority of cel collectors also collect for their 
beauty, and for the way they makes us happy. 
Which Kenshin closeup are you refering to? 
Because I just bought one in that price range. I 
know it's going to make me very happy^_^!
