I've used CCDC and found it to be good, however I and several others have shifted over to Sequence Generator Pro. Meshes seamlessly with PhDGuiding and Elbrus to give more functionality than CCDC.
See this site for more information which I've posted at another site and you could read it there. It's got a 45 day free trial of all functions so you can bash it to death. See
http://www.mainsequencesoftware.com/SGPro.html for auto meridian flips, plate solving as well as auto star selection and guiding.
I now use nothing else.
