I researched it on-line. It seems european xbox 360 can be used with US computer monitors with no problems. Eurpoean xbox can be bought from amazon.de. By some reason amason.co.uk does not ship them overseas.
And a step-up/step-down transformer (or voltage converter) should be seriously powerful. The one below will do, I think, for a console.

I am seriously contemplating this issue, not just to play DKS, but other european releases as well. It might happen that in the future they won't publish some european games in USA.
