Aside from being lucky to find one on location where can you actually go to play the latest Stern's?

What I don't understand is that they want you to spend $6-$10K on a pinball but as far as I know there is no showroom here in Perth where I can actually go and see the game and play it first?  I wouldn't spend that money on a second hand car without seeing it in person and getting to test drive it, yet there doesn't seem to be that possibility with a new pinball??
