For purchases abroad, use a Capital One credit card. They don't charge / swallow the currency conversion and international use fees, so all you pay is interbank currency conversion rate. Other cards might have ridiculous fees (minimums and up to 3.5% transaction fees). My only peeve with the Capital One card is that their online interface doesn't allow automated bill payment, so you have to do it manually once a month (and not forget). For ATMs, any large US bank should work fine abroad (anything that's part of the cirrus, etc. networks). Fees vary. Also try telling your bank to whitelist you for certain locations/countries.
