I have accounts that will let me use any ATM and reimburse me for any ATM charges. It is usually much cheaper than buying currency at home. Of course, if you are wanting to use US dollars then this probably won't work, unless the local machines give a choice of currency.
There is an ATM at the airport. Turn right after you exit the customs hall.
