I'm developing a series of regional guides/sites and need a good ad banner management system that allows for targetting ads across sites. Currently I'm using a C-based cgi-script system called CentralAd from CentralAd.com that has a lot of problems.

I've posted a thread at SitePoint Forums. See

http://www.sitepointforums.com/showt...?threadid=8490

I've gotten some replies from people recommending some systems or scripts and some third-party services that can do this kind of stuff for me. But nothing recommended so far has the flexibility or affordability I require.

I am hoping that some of you have used or have clients who use some good advertising management software that can be recommended.

Thanks in advance.
