As they said, the Plasma TV will not likely work unless it is multisystem TV. When our last TV died in the US I tried looking for one knowing I'd relocate to Europe, and they're pretty hard to come by. So unless you were specifically looking for one, you don't have one.

Most electronics manufacturers are wising up to the game and making 100 - 240AC adapters. Not all though. I got a 300, 500, and 1000W transformers and we haven't even taken the 1000W out of the box. I got a little 50w thing in a travel kit that we use a lot. My DVD player uses a measley 7 watts and I've got it attached to a 300W transformer. What a waste.

Your PC will probably be able to handle both 110 & 240, but be careful, they aren't usually automatic. There's a little switch on the back you have to change manually. If dont...kaflooey.
