Hi Simon and welcome,
Older Pavonis are easy to get bits for and with practice will produce a really good coffee. Plenty of local 220-240V options in Oz or even out of Italy from the bay of evil.
As to the Italian Style if it doesnt have a PF or you dont know where to buy one then its worth $1.50 as parts are going to be scarce and custom bits cost. A search over at Home Barista will get you some more info on it.
