See this list of CPM networks. The best are two from the top of the list. First pays up to 1.80$ per 1000 impressions of popup ( UK/US traffic, other countries = lower rates ), pays twice a month, through Paypal, with a minim of 100$. And the second one pay up to 1$ per 1000 impressions of INPAGE banner (also depending from the traffic of countries), also through Paypal/ E-gold, weekly with a 3.50$ minimum .
The greatest CPM program is, in my opinion, ADSDAQ. It lets you set your own rates and has a bunch of other cool options that you can implement. Here's my more detailed ADSDAQ Review. I also like The Rubicon Project because it automatically optimizes your ads. Here's my Rubicon Project Review.
