Well, we all know everyone's using adsense, still I'd love to hear what else are you using that gets you a decent monthly revenue.

I use:

Zangocash - Nice - Gets me 8-10% of my monthly income (yes, I know Nathan )
Adbrite - It sucks ... 0.5%
Clickcash - Another 0.5%, not much effort here.
CJ / Shareasale - 0.2% (I really can't play this affiliate game)
Adversal - 0.1% - Sucks more than the others
ValueclickMedia - Crappy, and I believe they forgot to pay me last month...
Chitika Premium (Thx Will for the affiliate) - My first try was ok. 2% monthly revenue. I'll try harder.

What are you using?
