Hey Aejsm,
Commercially in Canberra there is not a lot of choice - Capital Pinball, and Happy Days Amusements - both of which are located in Mitchell.
Of the two, it's really only Capital that has pins for sale, although Happy Days does have 2 Sterns listed (The Dark Knight / Spiderman). If you do look at purchasing commercially I'd suggest doing your homework re prices and definitely inspect any machine prior to committing.
Due to the lack of options most of us ACT guys look to the forums for our pins, but having said that there are always the odd bargains to be found on eBay / Gumtree if you are patient and careful. I haven't bought any from interstate businesses, but I'm sure other members here can put forward some respected ones.
Cheers,
Andy
