CD Transport for Rega DAC?

I am about to receive a new Rega DAC to go along with my Rega BrioR amp and Rega RS5 speakers. I am looking for a decent CD transport unit and am considering the following: Cambridge Audio CD30 (recommended by Hawthorne Stereo in Seattle), Marantz CD5004, or Oppo bdp103. The oppo intrigues me because it has the benefit of being a great blu-ray player, but I ultimately want the best audio. Your thoughts would be appreciated!
Thanks for the input. I have certainly considered the Apollo, but I am not sure if the price is justified since I really just need a decent transport to go through the DAC.

The apollo is worth every penny. It was made to be used with the rega dac. I would not try any other combo.
