There are numerous alternatives to Adsense littered around the internet. Most of them do not pay as much per click as Adsense, but are worth a try because of their alternative ad styles. Remember that you can now use Adsense together with other affiliate programs on the same page (so long as the ads do not look alike).
When choosing another affiliate program the most important aspect is whether you will get paid on time and the correct amount. There are numerous articles about other companies promising so much compared to Adsense and delivering so little. Always check the affiliate first by searching the web.
