We in Serbia if don't using Adsense we use Vizioshop affiliate program. That is a affiliate program that put them tshorts on your site and you will get 10% of each "stuff" solded. If you have warez forum (so you can't use adsense) you use this affiliate and you can earn about 300$ per month if is summer outside and if you have alexa rank something about 300k. If there is something about that in USA you can use it and this is a time for something like that

Otherwise for English sites i think that Bidvertizer is the best
