Thanks Christof,
Tradesports looks good for my purposes. Anyone know of others?
JayC,
I considered CBOE and options. But Black Scholes and others beat me to it. I'm looking for easier money. The sportbook traded bets have different features than most options, they are all-or-nothing and are easier to arbitrage. Options have variable payoffs after the strike price while sport bets do not. More importantly, sport bettors may be less sophisticated than the MIT PhD's working on Wall Street.
