Best Sub $500 used CD Player

Hello all
was about to buy an original rega planet used and then thought i would ask you all whay your ecperiences have been?
I have had the planet in the past and remember it being an extremely smooth and good looking unit. I have also had the mmf cd 25 and was impressed with it.
any thought on these two players or other options?
