Welcome to CardsChat.
Well, where to start?
First I suggest you peruse the 'Online Poker is Rigged' threads. Do this to get that notion out of your head.
Then realize the notion of variance, and how it relates to you and poker, either online or live.
Then read all the stuff here.
You don't show where you live, and mentioned depositing at Absolute and didn't mention any hassle. Suggests you live outside the states. In which case the world is your oyster. For us prisoners of the United States of Amerika, there are only a few sites, Full Tilt, my personal favorite, Poker Stars
, UltimateBet, Absolute, Bodog. There are probably many small sites that accept US players but word is not out on most of them yet.
Since you are playing at a level above micro games, any of the sites would be ok. Suggest you check each of them out, use play money till you understand the controls.
I suggest Full Tilt.
