Hi Nick,
Welcome to Aussie Pinball! I finished my home renovations two years ago with a goal of having 3 pins in the games room, anyway I now have 7 with plans for others. They defiantly bred, good luck keeping the collection at 3!
If you've been lurking for a little bit you'll have seen that it's a great forum and most people are only to happy to offer help and advice when needed.
Good luck with the house and enjoy shopping around a bit when it come time to purchase your first pins.
