I run a nonadult site, and use Google Adsense ads on it which generate decent revenue. As you may know, if Google doesn't have any relevant ads to display a PSA is shown instead.

I'm wondering if any of you know of any decent nonadult ad programs that I can use within Adsense to replace the PSAs? We've been using Amazon.com's affilate program for those, but we're really looking for something else (hopefully PPC).

I've got decent demographic information for our visitors too, if that makes any difference.
