There is one on eBay now with many bids , take a look >
  http://cgi.ebay.com/Korg-Pa800-Synthesiz...1QQcmdZViewItem  And others >  
http://search.ebay.com/search/search.dll?from=R40&_trksid=m37&satitle=PA800&category0=  I guess it all depends on how bad you want the E80 .
Sounds like you want one , so here is what I would do.
Put it on eBay ( auction + Buy it Now , option ) start the bidding at 1499.99 or BIN for 1899 and state free shipping for BIN. 
You will loss money either way , but not that much , plus the E80 is more of a board than the PA800.
( Look out for flying comments !! LOL )
Best of luck to you , take care
