If you keep an eye on ebay they do pop up. I have managed to get two from the US and been outbid on a few others. They were not advertised as selling outside the US but I sent a message to the sellers politely asking if they would consider shipping to me in the UK and most were willing - as the old saying goes "if you don't ask you don't get". The postage on these is high though as they are very heavy but surface mail keeps this down a good bit - make sure you get shipping insurance though.

Patience is the only way to get one but do not give up as you will get one and they are great fun.

PS. I will be selling one soon, it is new and never out of the box and it will be advertised to EU only but if I get a mail from outside the EU I will be happy to quote for postage if at all possible
