I have a couple of suggestions, and I'm listing the notes so you can see where/how I think they are similar fragrances. All three should be readily available (although the Colonia Essenza might be a bit harder to come by). The Eau Savage might be too lemony, and you might think it's too strong; so I'd lean towards the Colonia.
