You shouldn't need a converter for anything except for hair dryers and sewing machines.
Most electronics now have a built-in transformer that will work with various countries' voltages.
Look at the cable/power brick of your digicam's charger. It should have a voltage rating, i.e. ~110 - ~240, which means it's good anywhere. All you need is an adapter plug.
Same goes for iPods, electric razors, laptops, etc. etc.
