Are you selling a tangible product, digital product or both? Some networks deal with one or another,while others will deal with both. As mentioned above, ShareASale has been around a long time and they have a lot of happy advertisers and publishers. Clickbank is geared towards the digital products.
Have you looked into Amazon and Google. They both are giant affiliates and are more than happy to sell your stuff.
