I can't answer your question directly, but the 120v-230v problem is an issue American travelers regularly face with items like electric razors, blow driers etc. There are any number of voltage adapters available to allow US spec 120v appliances to be used in foreign countries with higher voltages, often location specific as the electrical receptacle configuration can vary by country. Should you consider purchasing a 120v projector you might want to first see if there is a 120v-230v adapter suitable for your area.
