They kill more trees than any book I know (except BOS) with their advertising and they will call you a lot. I've always stayed away from them because if they were a top flight shop they wouldn't need to be so pressure motivated. I don't blame them for being proactive but I've been told by players there that they can get to be a real pain in the a$$.
That being said I've not known them to stiff. I wish I could tell you more but I've never put money into them.
Parted ways with "Little" Nasa" (BetUs Sports) a few years ago. I believe they have ties to CRIS these days. I don't know if they have same hothead linesmaker (antny), but I would take Sportsbet's advice and check with Buzz.
