i know that it sounds cheap, but i only play at places with many freerolls, big offers& bonuses. therefor pokerchamps and absolute poker is my favorite online poker sites!
my guidelines are: dont play the money u dont have, get much free and dothebest with it
I think Paradise poker has the best graphics. They have good customer service. They offer lower limit games for two and four cents. These are a good place to learn. They are better than free because people play different when it is for real money. partypoker is a good company but the people that are animated freak me out a little. Full Tilt has good graphics and I have had good luck. They also have a generous buy in bonus.
I also love the graphics at paradise poker, and the low limit tables. I do miss the freerolls and have started playing at pokerchamps, they have one on the hour, and play to 28 places. I occasionally play at party poker but do not care for there graphics.
I really enjoy paradeise because the site is straight forward and no matter what your limits you can always find a solid game with the best players on the net from my experiences
