Affiliate Programs Best popunder program?

[fryman04]

I have an average of 1,500 popunders at my site each day. I am now using paypopup,com, but they olny pay $1.3 CPM.

I found a site called infinity ads, and they pay an impressive $3 CPM. Has anyone used them? Are there any other sites you might recommend? I'd like to change my current program in November (just want to get to the minimum payout amount at paypopup), so any suggestions would be appreciated

Thanks
