I am trying to find an online sports betting website. which is the best website to go to? I also live in Missouri ive tried a couple of sites cant remember which ones and went to go sign up and when I clicked on the state that I live in it didn't have Missouri on it.

Well, check Gambling Safe, it has nice reviews of sportsbetting sites, you can find the section for USA friendly bookmakers here http://www.gamblingsafe.net/usa-friendly-sites/usa-friendly-bookmakers.html
I like bookmaker and intertops. Bodog is also not bad.
In the reviews you will also find info how to deposit(depositing from USA is harder than in other countries).

As someone who places thousands of dollars of sports bets every week (and wins thousands more every week! ; )), let me tell you that finding a reputable online sports betting operation is a pain in the ***, especially if you're in the States.

This is what you should look for:

1. Smaller is better. If you bet with the big boys, you get lost in the fray and good luck getting your money out. If you bet with a smaller operation, the customer support is better and they really care if you complain. Plus, getting your money out is way easier.

2. Big Bonuses are NOT always better. A lot of companies will try to entice you with deposit bonuses, but its always a pain to try to cash that out. Read their terms and conditions carefully before sending your hard earned money out the door.

3. Check for reviews regarding the "payout" or "cashout" experiences other players have had with the company. This is usually the best indicator of whether they are reputable or not.

I personally use a few different ones for different sports and different types of betting. There are independent reviews, written by me, at http://www.Sportsbook-Ratings.net I've been using these sites for 10 years, and I know which ones to use and what sites to avoid! All of these sites offer great sports betting offerings, exciting casino games, and exceptional poker play. The recommended sites all offer excellent customer service, security, and easy deposit and payout methods. In addition to the certified independent reviews, you will find free daily sports picks, betting tips, and much more.

Bookmaker
My favorite all-around sports betting site is http://www.Sportsbook-Ratings.net/BookMaker.php They are the first ever offshore sportsbook, and offer the earliest betting lines, which is important to me, free payouts, and they won't kick you out for having a winning season! Use the bonus code FREENFLCASH for their absolute best deposit bonus!

betED
If you want the site that is easiest to deposit into, then http://www.sportsbook-ratings.net/betED.php is what you are looking for. They have great service and offer eCheck deposits, and easy credit card deposits too! They will also pay you via electronic check for free. This link qualifies you for a huge bonus :)

Intertops
For variety in wagering offers...like stock markets, reality shows, and world sports, you may prefer http://www.Sportsbook-Ratings.net/Intertops.php Intertops was the first online sportsbook ever. They are good for recreational bettors, and offer free bankwire payouts once per month.

2betDSI
Diamond sportsbook, http://www.Sportsbook-Ratings.net/Diamond.php , offers early betting lines, dimeline wagering for baseball, and professional action is welcome. Also, if you enjoy casino action as well, you will enjoy using the highest certified payout percentage of %97.9! DSI welcomes American clients and special bonuses when you use the bonus code NFLCASH09
