After reading a lot of post about using ATM's instead of taking $ or exchanging $, I've decided to go the ATM route. My bank is on the Master Card/Cirrus network, and Master Card has a great ATM locator feature on their website.
Master Card ATM Locator.
Simple to use. Select Netherlands from the country menu, then enter Amsterdam as the city. Note: The results page only lists 10 hits at a time. You may have to use the drop-down menu on the results page to get to a location near your hotel or apartment. I found two ATM's within two blocks of the apartment I'm renting.
Cheers!
