Which IM Business Management System

I am looking for some quality feedback from those experienced members who have multiple sites earning a regular income. Most likely because od the volume of sites you operate you will have some sort of management system in place. Which gives you a list of all your sites, their history, their earnings etc.... . The sort of systems are similar to Ektron CMS400 but far too expensive for me to even contemplate. What management systems are in the market place to do this and what is your experience? it would be great to get some feedback from you.
