Rates are very cheap but some time good for nothing. Before buying any pop-under or similar you should check 1st that company can deliver you actually that no. of pops under your defined time. You should also check where those pops would be popping up or they are popping in any dark corner of the web where no one sees them. Good advertising companies charges quite high. I am also looking for similar solution but still searching good advertising site at lower rates.
as mentioned targeting is crucial, unless you have a serious budget and are interested in branding aswell.
Dont forget the Creative will have a major effect on your CTR.
Do let me know how you get on.
