You may want to check out the new Arcam CD33 with upsampling. Otherwise the CD23 (which I own) is also a great choice, especially if you can find a used one. When I shopped for a CD player, I preferred the CD23 over the Rega.
That said, I don't think you can go wrong with any of the players you listed. It's just how well the player matches with the rest of your system.
