At a fair price, and if you have the space, you ain't got much to lose. For me this would be a "couple of games then bored with it, rinse and repeat every few months" scenario.
There is a reason why these things are dim and distant (1970s and early 80s) memories for us. They were never that great. There were loads of things I remember from back then that just fell by the wayside as tech improved. Today, I would love to play them a couple of times - then move on. Like when I was a child in the arcades. That was what they were designed for - catch your attention. Play a couple of games, then onto the next one. The arcade had 10, 50, 100 games to try.
Coin operated stuff that made it into cafes and sports centres as well as arcades - like Pinball, skill with prizes, fruities, table football, air hockey, video games, juke boxes .... There might have been 1 to 5 of these in the cafe or sports centre. They were designed for more repeat playing.
They are still around today as they are superior products for the home user unless you have a big collection imho
