A related tip: I've always found it best to wait and buy the adapters and converters you need in the foreign country instead of at home.

That way you're guaranteed that the salesperson will know exactly what is required in their plugs, and you'll know the US side, so you won't make any mistakes.

If you buy it in the U.S., you have no idea if the salesperson really knows what they're talking abolut for the foreign country.

BTW, if you're in doubt on any other equipment to know if you need the converter or not (a U.S. - side question), err on the side of using it. It certainly wouldn't hurt anything to use the transformer when it wasn't needed, but it could definitely hurt not to use if it were needed.
