I was banned from Google Adsense for auto generated content. (no big deal) However, Since then I have used Conjunction junction, linkshare, amazon, yes advertising, (in text ads) and nothing seems to work that well like google adsense. My site gets about 200 a day and continues to grow slowly. (http://www.bestoftheinternets.com) I would grow / develop more if it made more money... but with out good adsense the CTR rates aren't that great, so focus on other stuff.
Yahoo/Bing and some of the other advertising companies won't deal with you unless you have 10,000 hits a day.
Any alternatives, thanks in advance.
