Hi,
Interesting question :
Arbs are definately wot some mebers here would be looking for - so long as u can guarantee payment from both sides.
www.bookmakersreview.com gives a guide as to the good and bad.
I cant find a rating for matchbook.com, whic I take as a negative .. but, a positive was this press comment :
Elsewhere, Matchbook.com officially launched its online betting exchange, following its successful spring 2005 beta launch.
The Antiguan-licensed Matchbook already has more than 2,000 users which match $10 million in bets per week.
According to Tom Ramsey, Matchbook's Vice President of Development, American sports bettors are taking to exchange betting even faster than their European counterparts have to date.
"Exchange betting has already shaken up the $30-billion European sports-betting marketplace, and now the North American market is experiencing a similar transformation."
"The North American marketplace has seen only one significant development in the past decade: the rise of online sportsbooks, which ended the monopoly held by Nevada-based and illegal bookmakers," explained Ramsey.
"But online shops still book by the same old rules. As the Europeans have demonstrated, when people can bet directly with each other, betting markets become notably deeper and offer much tighter spreads," he added.
So, maybe its worth dabling with .. if u fancy chasing your cash from an Antiguan based company.
