If you wanted to buy a new Stern Pro machine every year, you would need, what? $4500-$5000? Something around there? That's $375-$417 per month that you would have to save every month. Obviously, we're talking upper-middle class ($100K and up), but those are the same people that lease fancy cars and go on vacation every year. I think they would be able to swing that much in place of something else, if they liked pinball that much.
