Which site pays the best on a CPM basis?

I can’t find any other site beside Adbrite that pays on a CPM basis. But Adbrite takes 4 months to get payment from and to clear a check from if you live overseas, so it’s a hell of a long time to wait.
Any other alternatives?
Why can’t Adbrite have their accountant just spend 20 minutes signing up with a PayPal account instead of making me wait 4 months just to get a $25 check?
