I use Full Tilt. but I hear that Poker Stars is better. You can join and play for free
Poker Stars is good for freerolls, as well as Full Tilt. You might even want to consider real money, on sites like Poker Stars, the deposit minimum is as low as $10. Check the reviews of each at http://poker-lobby.com and http://dagus-statistics.com/reviews to help make an informed decision. Hope this helps.
32red offers 10 x $10 free rolls every hour.
I always prefer CoolCat Casino.

Pitbull Poker has freerolls every hour, Carbon Poker runs freerolls every 4 hours and both accept USA players. Gear Poker has 17 freerolls per day but does not accept players from the USA.
I would say Actionpoker, because it is a new site and only has a few hundred players in every freeroll tournament. This Highly increases the chance of getting some money. Freerolls are run every hour.
By the way, there is actually no need to play a freeroll tournament. There are sites offering you free starting capital of 100 to 150$. This way you won´t have to spend hours and hours playing freerolls to get a lousy 4 bucks. Learn more from http://www.howtoplaywinningpoker.com it is all explained there.
Best of luck to You!
