I am looking for FREE, honest betting tips and advice. I enjoy betting, but would like to know more inside info before placing a bet, especially on horse racing and football (soccer).

I can suggest 2 sites.
The first is sportsinsights.com
This site is free and it gives you everything from a team's trends to public betting percentages. A lot of good info on there to handicap with.
If you want to skip handicapping and go with the experts, you can go to www.cappersaccess.com This site has handicappers picks. These guys sell their picks for hundreds of dollars sometimes, but you can find their picks for free on here.
Good luck!

For sports betting, I suggest http://www.1betus.com/sportsbook

http://www.bettorup.com offers great tips on sports betting and is also a free sportsbook. Check out the forums.

thefbz.com is the best place to look on the net for tips and free service plays

I am quite a big user of Betfair, and with varying success.

I quite like their new blog - http://betting.betfair.com. It provides tips and articles from a number of different professional sports players and gamblers. You should check it out.

Because Betfair is an exchange, they actually want you to win, so I don't find the information here biased at all. Just do a search on the internet and all the top tip sites will come up. The one mentioned above is definitely a good one and a decent read too. I don't really use any others - just regular sports news sites like the bbc.

Hope this helps...
