I have taken advantage of the exclusive deposit bonuses at:
Slots of Fortune
The only one that actually didnt rob me blind was Cocoa, where I was able to cash $650 via ach in 2 days.
Looking for a 500%+ bonus. I have pretty much gone through the list the only other's I can see are the Rogues, Slow pays and the vegas days/rock bet/this is vegas group that show a high percentage deposit bonus but it is nowhere to be found.
