AdManagerPro is very good. Great support and reasonably priced. I prefer it over OpenX. Can serve a lot very fast. A good turnkey system, with enough flexibility. And it runs on a more diverse array of server configurations (less finicky). AD sales process is good for the customer and easy for you. Learning curve no too bad.
