Cambio at the airport

I've taken out around $2k in one day in Mexico, no problem.

Their customer service is great... Once had a card expire while I was in Iceland (I had not opened my mail to get the new one before we left.) They overnighted me a new card to a hostel in the middle of nowhere, free of charge.

I couldn't recommend it more highly. You have to open a brokerage account to get the checking account, but no minimums. You can apply all online.
