Good to see this list.I personally tried Azoogle & Hydra. There are good. But I would add www.Aptnetwork.com in the list.
These guys does not have too many offer like azoogle but Aptnetwork.com is payout is really high compare to others.Sometimes you need to have good contact with your affiliate manager to get going.Just my 2 cents..

Very interesting how you explained it. I sort of know it intiutively but your simple and short explanation is helpful and recommended without reservation. I will make use of your suggestions in my current search to set up a good affiliate business. I recently signed up with ClickBank and is looking to market other people's business and earn money doing it. Your post is really helpful.
