Bring the Wii man. The Wii has its own power brick, similar to a laptop. You can buy the 220v version of that brick here. So bring it.

As far as your Sony LCD, I'd take a look at the back or the manual. I know a lot of tv's are dual voltage these days. The only thing I'd be afraid of is getting it here in one piece. That alone would make me leave it behind ;-)

All your other small stuff. Leave it. You can pick that stuff up here. Just pack light and don't forget your passport, lol.
