The good thing about Ranma is that he's cheap. :) 
Well relatively cheap -- he's not in the 
Evangelion category. I basically collect cels 
from the first season and the OAV, and quite a 
few have been showing up lately. I wish I had 
more Vans. There have been some really nice cels 
turning up, unfortunately most of them have been 
out of my price range.
