Where to get a used Hales Revelation Center Spkr.

I own a pair of revelation 3's and am looking for a used revelation center channel speaker. I have been looking in the online classifieds for a long time and have not seen any for sale. Does anyone know of a place or a person that has one for sale?
I've been looking for one to go with my Rev3's for a while too. There seems to be virtually no turnover when it comes to used Hales product.
I saw a pair of Revelation Ones here that may or may not work for you as a center channel. You would be extremely lucky to find an actual Hales center channel. I routinely check for used Hales on the various cites and have never seen one. Good luck
