$20-$26 Sportsbooks: (via CC):
1. Bovada (don't know if they're still accepting U.S.-based customers) ($20 + small processing fee-1-2%)
2. Betonline ($26)
All accept MG & WU (most carry a $50 minimum with this method, although BAS has a $100 minimum w/ this deposit method)...
Hope this helps....BOL
