I know I'm in the (vast) minority here; but I like both casinos. As a US customer without many places to play, I find both of them attractive.
Silver Oak has been trying to get out of the pit, and, correct me if I am wrong, but I don't believe there are any/many outstanding issues right now. I know the rep has been trying to clean them up (see other thread).
GrandParker has always paid me, even large numbers, at the steady rate of $1000 every two weeks. Not the greatest, but it's steady and I know in advance what I'm getting.
Are there places that pay much faster? Absolutely. However, if you like numerous, very generous bonuses to increase play time (which I do), then I like these two casinos.
No, I'm not a shill, but I do believe that what I said above is accurate.
