Quoted from Rarehero:
That's what I'm doing from now on! I've got my Ghostbusters Blu-Ray....my Lebowski Blu-Ray...don't need the pins for them. For the cost of a pinball machine, you can buy a whole bad-ass projector home theater setup and still have money left over.
Pinball is expensive but there are other hobbies that are even more expensive. Boating can be insanely expensive between the cost of a boat, storage, maintenance, etc. Same goes for sports cars, higher end cars or classic cars. I cant tell ya how many people buy $40-$50k new cars and then have $500-$700 a month car payments, and then pay $120+ per month for car insurance.
Part of pinballs comeback is that it's a game that exist in the real world in a world where nearly all games are digital. Humans will always have the desire to do and control things in the real world over simulations. Its the reason why manned space exploration will continue over only robotic missions, why people will continue to buy classic cars over playing them in a video game, and why nearly everyone will continue to take vacations vs putting a VR headset on for a simulated beach view.
