Dude, if u need a decent ad server as an alternative to OpenX, I'll suggest. Trafficspaces.
I designed it and it's one of my proudest pieces of work (if I may say so myself) :)
Warning: its a premium service

Assuming $1 CPM, a site will be making $1000 off of that. Your taking a 10% cut.
$100 should get you 50,000,000 impressions, at minimum.
That's where Trafficspaces excels - ad targeting.
All impressions aren't equal so you shouldn't treat them as such. The key is being able to unlock the value.
