It depends if the keyboard has got external or internal (bulit in) power supply. If external you can just buy some power supply for US. Sometimes the internal power supplies accepts 120v and 240v then you can just plug it in... if not you can use ac converter like this: http://www.threedoubleyou.com/convertpower.htm

Shipping prices you can find on: http://apps.dhl.co.uk/cgi-bin/calc.cgi

What keyboard is this?

Wow, That was a while ago, since then I have purchased a Kn7000 here in the states,

Thank you for trying to help.
