In case you didn't know it, Neteller takes Vis a card deposits. It will cost you an extra 1.9%, but you can wind up depositing almost anywhere, and have it credited back to your Neteller account without the usual CC hassles. If you deposit enough, you can pick up one of the bonuses like the 21% at the Greek, or 10% at Bodog to make up for your extra % paid to deposit with Neteller. You can also ask the book you deposit with to refund you the 1.9%. They might.
CRIS also just sent me an email that they are excepting that pre paid ATM card now and will give you a bonus for using that method. It can also be loaded with a Visa card although I don't know at what cost.
