I'm having my own issues with Intertops at the moment, so I too am not pleased with them.

You can try Bovada if you're looking for an alternative. I've experienced near instant withdrawals via MyPayLinQ, but there are some hoops to jump through initially to get started.

I should add that I've heard reports of slow payments from Bovada, but haven't really looked into it because I haven't had a chance to play much lately.
