Pop up/ Pop Under networks

I am looking to place pop up and or pop under ads on my site.I am having a tough time finding any networks that specialize/focus on it other then porn ad networks. Anyone have a recommendation for a list or just a good individual company that does pop up/ pop under ads.

thanks

This is very old thread and user may not be active or looking for pop up ads anymore

Though I would still like to update it with my recommendations, I am using eDomz.com and find it very good and earning very good with display ads, if anyone else looking for display network, I would recommend it
