Hi Everyone, I'm interested in buying this projector while I'm in Japan. 1/ It looks identical to the VPL-HW40ES - does anyone know if there are any differences? 2/ It is listed as only supporting 100v input, so I have the option of buying a transformer but apparently all Sony projectors have switch mode power supplies capable of 100v-250v 50/60Hz. Does anyone have any experience with this? Thanks for your help.
