In the few series I collect, I have never seen 
better cels for sale ANYWHERE else.  Most of the 
rarest cels I've ever seen have been on that 
site or in people's galleries who have gotten it 
from them.  Im concerned they don't note damage, 
however the actual cels (openings, very 
desirable scenes, etc) they carry cannot be 
compared, IMO.

Getting an IPMO isnt very expensive or a hassle.
