You could try BidVertiser to advertise. Personally, i like them. If you are a publisher or an advertiser. The referall program isn't have bad either. Every user who signs up with your Referal link, when they reach $10 in their account, you get credited $10, if they make $50, you get another $40.
plus, same idea though. have the money to put in, you will get more visits. another thing, they aren't strict on account terminations. if they beleive you to be clicking your own ads, they simply send you an email, saying it has been detected, please stop. Unlike Google, even if you report an accidental click, they delete your account.
