hehe u’ll probably find hundreds of like lists, it’s a matter of preference and how you’re treated, how much you make, mixed with available geo locations.. Couple of the favorites are 32red and poker.com I persoanlly like revenue giants.. and anyone whos stats don’t lag 
(which doesnt include rev giants )
The affiliate manager at 21.com is cute as hell .. i’m not a guy though, so I’m sure i dont fully appriciate that, and sweet as pie, she’ll go the extra 10 miles, or does for me.. so that’s another of my faves..
Mark @ FocalPoint is great at getting right back with emails, and setting up promotions.
Absolute poker is easy to work with with lots of banner choices… Income access has a lot of properties..
It’s all really a matter of what you’re looking for in a program, which you probably wont be fully sure of for a few months to come.
