any one tried Casale Media for Popunder/Banner network of the highest quality they say : The payout rates for popunders are comparable to what we are currently seeing from Fastclick's pops, campaigns average out to $3.50 - $5 CPM gross, of which Casale Media takes a flat 30% cut. The remaining 70% is yours and in our case works out to between $2.50 and $3 CPM.
Casalemedia is one of the best networks I have been with. It's not only because of the pay rates, but because they don't just accept anybody meaning that they have better payouts and higher quality ads.
The Best CPM networks in order: 1) Tribal Fusion 2) Casale Media 3) Valueclick Media 4) Burst Media 5) CPXinteractive Tribal Fusion is the holy grail for CPM rates and advertisers, but their requirements are really high and only a selective few will be accepted. You may want to try the others if you can't get into TF they have lower requirements but offer good CPM rates.
