Best Stepdown Converter

Hello!

I bought a US Xbox One and intend to use it in Denmark, so I'm looking for a 220V --> 110V converter. I've searched around for hours and only found $70+ converter boxes and $70+ original PSU's on eBay. There has to be a cheaper/smarter way to do this. Can any recommend any specific products I can use?

Thanks! :)

Cheaper than $70 for an original PSU? Good luck mate.
