Overclockers have plenty in stock:)
I've used the site dozens of times and they are really good.http://www.overclockers.co.uk/productlist.php?groupid=701&catid=56&subid=1842
Do you still need help?
I went for the one on overclockers, I saw they had some, but I was dubious about them, but at the end of the day I have heard some good things and I can get my money back pretty easily if anything does go wrong.
Those ones on ebuyer and novatech aren't showing up for me, weird.
