$500 used CD Player Recommendations

I am looking for recommendations for a quality used CD player in the $500 neighbourhood. This unit will go into a small secondary system in my dining room, based around a NAD c352 integrated amp & Monitor Audio Silver monitor speakers. A few players that I have been considering are the Rotel RCD-1072, Music hall CD-25.2, Cambridge Audio Azur 540C v2 or Cambridge Audio's Azur 540c v2 or 640C v2.

Any thoughts are greatly appreciated.
