As far as I am concerned, Adbrite is a very nice advertising application which pays well. The minimum payout is also low when compared to Adsense.
They will pay you via paypal. I have a very good experience in Adbrite as i was able to place my ads soon on my blog.
Adbrite is considered as a very good alternative to Google Adsense as they are very strict in approvals and payments these days.
