Which Ad Network Isn't Evil?

WaldoJ writes: "One of my sites, nancies.org, has been doing very well, traffic-wise. Hundreds of thousands of page views each month. But our banner provider, ContentZone, is fundamentally evil. They've been sued by their clients, and they don't pay us enough. Flycast has been bought by Engage, and they're apparently not so hot either. DoubleClick? Don't get me started. It would be great if we could run the site without ads, but the hosting alone would kill us. We tried the donations route, but that's no good. My question is this: Which banner network is the least evil? Which lies the least? Which pays the best? It sure would be helpful to get some input." If you have to have ads for your site, it would be nice to get the most out of the hits your site does get without the hassles. Any recommendations?
