Well

I would say most dealers has been to Japan 10 
times or more, yes, Japan is fun, but honestly,
 when you go there once per month, it may not be 
that fun.

Sure most dealers probably sell cels as a hobby, 
that still does'nt mean they don't have the right 
to charge what ever they like.

I would say all dealers treat this as a hobby, as
 you know, dealers has awesome/super expensive 
cels in their collection, most of their profit, 
probably go towards their collection anyway, so 
what wrong is that.

If you go to Japan and try to look for cels, you 
will appreciate the dealers more.
