Quoted from indybru:Maybe you should keep your eyes on pinball shows by you and see if you can snag a demo game for less after show.
Contact Marco Specialities or similar vendors with a big presence at your local shows, and see if the have a show game program. I got my IMDN pro as a show game from Marco at SFGE and basically saved the entire NIB hit - I think I got around $800 off for a game with 300ish plays on it.
I was also credited with being a game bringer and got admission to the show everyday for free. Another $50+ benefit.
