So the seller has to acknowledge up front that 
they may NOT resell for even close to what they 
paid. That goes double if the market is volatile, 
like production cels. On eBay over the last few 
months, Sailormoon cels went for under $100 when 
they would have sold for several hundred just a 
month or so prior. (SM first season OP cel for 
$66 - wha?)

Value is subjective. And you go to eBay because 
you want to get a good deal, and b/c buyers have 
more power over pricing. If you're a seller and 
you want to try and "recoup" what you paid, then 
try asking a dealer to host your cel for the 
price you want.

Economically, what you paid for anything is a 
sunk cost. You can't realistically consider it 
when you resell. You essentially traded money for 
whatever value/pleasure you derived from the 
item, and when you resell it's the potential 
BUYER that determines it's monetary value, not 
you. 

zefyr, if you really want to get what you paid, 
contact a dealer, wait out the slump and hope SM 
gets popular again, or just accept the fact that 
you're going to take a "loss".
