I'd give directbet a 3.  Really, it's cool and a good idea, but the lines are just SO bad sometimes.  And, it's supposed to be great for live betting but really half the time the bet you want is not available, or they only have 1/2 of the bet you want (i.e. Royals v. Red Sox, they only have a line up for Red Sox to win but not Royals, even when the game is close)
