One thing to watch out for: Some of the voltage converters that are marketed to international travellers in the U.S. don't use transformers; rather, they are half-wave rectifiers (essentially big diodes). A lot of the higher-wattage (500W and up) are made this way. They are usually marked "for use with heating appliances" or some such. They're okay for hair dryers, but the rectified waveform will destroy a lot of power supplies! Whatever type you buy, and particularly if it's a higher-wattage model, make certain it outputs a sine wave and is rated for use with electronics.
