I have seen several pairs on eBay, I watch them to see what they are selling for.. I have a nice pair myself and have no desire to sell them.. If I did upgrade it would be to a pair of Chorus IIs... When you buy on eBay you can ask a seller if he will be willing to use an escrow system. Escrow allows you to inspect the speakers before you release the funds to the seller.... you will have to deal with enormous shipping costs if you get a bad pair...If you do purchase a pair ask the seller to remove the bases of both speakers and ship them separately..
