Cfl y-splitters

Australia does not sell y-splitters due to australian standards being silly, so I was forced to take my search online. The only y-splitter I can find is at http://www.farmtek.com/farm/supplies/ProductDisplay?catalogId=10052&storeId=10001&langId=-1&division=FarmTek&productId=42515 and only allows 2 x 13w bulbs I think. Does anybody know where I could purchase a good one online? Or failing that, how easy/safe it is to make one?
Thanks RIU!
