i am going to set up an ad network and a banner exchange. if possible i would prefer having both concepts in one script. but if not, i would like to hear your recommendations on the best paid and open source scripts for each concept.

for ad network scripts,

i checked openads (old phpadsnew), i used it before, it is not what i need. i am using revsense, it falls a bit short on features. i checked some other paid scripts. but couldnt find a good deal yet.

for banner exchange scripts,

i dont know zit about banner exchange scripts.

please give me a bit of directions on this.
