I like CJ, because they have high quality advertisers... but you have to be careful when you're posting your affiliate link. You have to register every page of your website on which you want to include affiliate links, then when you want to post an affiliate link, you have to indicate that on the link creating wizard. It sounds more confusing than it really is, but it's something to consider.

Linkshare also has the same high-quality advertisers, but creating affiliate links is easier than CJ, and you can post the same link on different pages of your site (although you may not want to do that if you want to track the performance of specific pages).

In principal, Clickbank would be the best and the commission is very lucrative, but a lot of the products I have looked into seem to lack in quality a little... and they just have this funny feel about them, in my opinion. I hope I do not offend anyone, though... I am confident, however, (in fact, I know) that there are some high quality products on Clickbank.

Let's see what else... I have some success with Azoogle.com - they focus more on paying commission for lead generation, but some of the commission is nice.

Most Importantly, when you sign up for affiliate programs, make sure to stick to the ones that match the interests of your specific population (your niche)... but this point was brought up in a previous post (I just wanted to emphasize).

I hope this helps.
