I got it a while ago on ebay from a seller/store called Australia Games (actually UK based) but searching for it now I can not find another copy. There are a few of the other CE for fairly cheap (the book one) on ebay, which is what I meant to get when I bought my edition. I feel lucky now since these flashlights have turned out to be quite hard to find .
They are the 4 sources I use to find cheap games. Not only that, but Ecogamer has user 'service reviews' for many online stores (Zavvi, The Hut, GAME UK etc.), which helps if you're looking at importing and want the cheapest and safest delivery.
