Choose the more popular poker sites. Look at how much traffic they get monthly. A poker site that has a thousands of active and regular players at any given day tells you that the site is reliable.
At this writing, the three most popular poker sites on the internet are:
2. full tilt poker
3. ipoker network
At any time of day, you will find a good number of players on these three sites. You will have a large number of tables to choose to play in. If a table doesn't suit you, simply close out of it and look for another one on the lobby.
I have real money account with these sites and have been playing for more than a year now. Getting my money from these poker sites aren't that complicated. When you put money in using a debit card, then that's how you will be able to get your money back.
I deposit funds to my account using my visa debit card. It takes less than a minute to do that. Withdrawals will take about three days.
Enjoy your day!
