iPoker cashback deal, which one is best?

[Koalaboy]

found some iPoker deals that were interesting on silverrakeback.com , I'm particulary interested in the one offered by Chili Poker (1000 points for 20$) can someone calculate how much rakeback % that would be? or is the NoiQ VIP offer still better? or the one of Cardoza (5000 points for 40$, but you can keep the points to use).. any math brains.. do your thing [img]/images/graemlins/smile.gif[/img]
