The ebay feedback system has some annoying 
issues. Ever have a seller wait to give you feed 
back, even after you've paid, and recieved the 
items days later. It often seems like there 
waiting for you to move first, keeping their 
option of retaliating with negetive feedback 
open. Course everyone on ebay seems gun shy with 
the feedback, your at the whim of some almost 
entirely unknown individual. Also, how valid is 
feedback, people tend to leave positive feed back 
that would often be more descriptive of a saint, 
granted there hoping for an equally favorable 
review. Ebay's been called a community but really 
has little relation to one. 

Just my 2 cents.

Also, theres always the animanga auction.
