I thought you would be interested in checking out Tennis Betting Odds at http://www.tennisbettingodds.net.
Tennis Betting Odds is a handy resource for punters. It contains an odds comparison service, match and team statistics, and a computer prediction service which analyses the tips of experts in tipping comps/prediction leagues to let you know what the pros think.
You can join in the fun of these contests and prizes are up for grabs (typically free betting money).
Tennis Betting Odds also has a "value bets" section, which compares the computer prediction service with the bookmakers' odds to let you know where value is and isn't to be had.
