Maybe try keyboardco on Amazon.co.uk? I'm not sure how much shipping would be via that route, or if it's even possible to purchase from Italy (I would think so, as I believe people have purchased from the US before...).
Also, elitekeyboards ships internationally to some countries. Again, not sure if Italy is on that list. But I don't imagine it would be that much just for shipping. And the plus is that Leopold puller is one of the best I've ever used.
