Tourney Blackjack Profit Potential?

[SunOfBeach]

Anyone here have any idea of how much opportunity there is in tournament blackjack? I'm referring mostly to the quantity of tourneys offered (particularly ~100% payback tourneys), the size of the entry (are there HIGHish stakes tourneys out there?), and the potential to 'play the circuit' or anything like that. Basically, if someone could refer me to a site/number,etc where I could learn more about the metagame of tourney blackjack, that would be very appreciated.
