110-240V Transformers

Sadly my trusty travelling XBOX is a 240V only model (though it works quite happily on the 60Hz 220V here in Korea), and I will be heading to Saudi Arabia with it later this year, so will need a 110V-240V Transformer.
MrsPVG won't entertain the idea of me buying a shiny new 110V XBOX360, so do any of our transatlantic flyers have any recomendations for a compact transformer?

Thanks

Places such as Radio Shack sell them. The one thing to look for is the wattage requirement of the XBox. You will need to get a transformer suitable for that wattage. They start around $15-$20 and go up to over $100.

edit to add: Apologies I now see you want an Step UP transformer. Same principle applies but I guess you need to source in the UK. A quick search on Google for 110-240 step up transformer yields quite a few good results. Maplin seem to do a few
