Step Down Jap To Uk

i am trying to find a step down transformer which will allow me to use a jap saturn/neo cd, in the uk. i have seen a lot of US to UK transformers on ebay, are these the same or do i need a JAP to UK one?

get yourself a sunpower ac-ac converter.The output is 110v at 45w. it plugs into a uk powerpoint and the plug output arrangement is for a 3 prong USA plug,if it has an earth, but a jap 2 prong plug fits as well because the spacing matches. You can get one from maplins and cost 20 quid. I use my jap neo cd with it and its spot on.
