What Is Your Favorite Affiliate Network?

I've been using affiliate networks for many years. I primarily look for the merchants I want to work with and pay less attention to what network they are on.

Since I like to work with major merchants, this has led me to spend most of my time with Commission Junction and LinkShare.

I always thought that affiliate marketing would have advanced much more by now. I thought we would have more dynamic links (especially for updated coupons) and more links available.

I wondered if this was because I was only working with the big networks so I started joining some of the other affiliate networks such as Share A Sale and Google Affiliate Network. I am finding the same problems.

Does anyone work with an affiliate network that they are in love with?

I have been hearing good things about AvantLink, but I hear they don't have too many major merchants?
