There are 5+ banks in my local area and all of them support foreign cards. The only reason to go out of your way to use a CCB ATM, is if you are trying to withdraw from a BofA account; otherwise, those guys hit you with close to $20 in fees. I'm in the process of moving away from BofA myself because: 1) my CCB ATMs frequently run out of money on Sundays; and 2) CCB doesn't have very good coverage in Beijing.
