I think that it's a good idea that the prices are 
removed.  A) Once a cel is sold, it's no one's 
business what the buyer paid for it. 
B) If you see a great sold cel, you won't kick 
yourself for missing it cause it had a cheaper than 
cheap price.  
C) And lastly, if you know the price on a cel and 
later you see it on eBay for a a fortune more, then 
you won't want to kill people as a result. Like the 
Bugs Bunny cel that sold at one dealer for $25 and 
later on eBay for over $125
