For ads, I don't think others pay quite as well, and even those that come close, usually require at least 100,000 uniques a month or something like that.

But if it's not too irrelevant to that topic, I suggest combining whatever ad network you have with Amazon affiliate links. It helped me double my Adsense income for the same traffic.

Ultimately, if you have some quality service or content that you can sell, membership/subscription model is the best. I know someone who just gave up on Adsense, and was making 10x the Adsense revenue from subscriptions.
