Edward, no your not ignorant,and you are excused

fairly sensible question, i had great difficulty,in finding ANYTHING ,out about import models ,and obviuosly the co`s make it as difficult as poss. for us to find out, i was lucky in that i have a friend who lives in Tokyo,and he spent loads of time trying to suss out the model differences......it`s a 9000 `E` in the UK in the USA it`a 9000`U` etc.etc. i have got a plain 90009but i have been told that maybe now they are all just 9000`s) but apart from 1 connection in the back (for a D4 connection...........don`t ask `cause i don`t know !!) it`s the EXACT same,and it has been checked over by a sharp dealer in Glasgow,and he says NO difference at all from the UK spec one.....apart from the fact it was £5000 cheaper,totally ridiculous,yea they are all multi voltage so all you do(as you say) is buy a kettle or computer lead and plug it in..if you neeed any more info just let me know
