Reel to reel tape

Question: I am selling my reel to reel Tanberg TD-20A. I have searched the listings on eBay and here but I have found no reel to reel decks for sale or sold. Any suggestions what I should ask, given its excellent condition? It is still in the original box and was factory serviced before it went into storage. It comes with lots of tapes, of course.

Any suggestions would be most appreciated.
