My wife is just about as into pinball as I am and she keeps telling people that we will move more things out of the way WHEN we get more pins to make room for them. So she "kind of" enables me and just says "As long as we can afford it". That's cool in one way, but I'm going to have to throttle back on NIBs though. Maybe start to sell/swap out when I buy more, now that a reasonable collection (count wise) is established.
If you're not into boats, ATVs, snowmobiles, big extravagant vacations, or non-entertaining collectibles, I think this is a good hobby to have as a trade off. Expensive for the more modern pins - yes! But I would rather have a NIB pro pin than go to Hawaii for week for both of us. The pin entertainment time volume is decent for my wife & I at this stage in our lives.
It is kind of funny though. I weigh some expenses based on a average NIB pin price. Put a patio on the house that would hardly get used, or buy a pin? Pin won for the last 2 years. May not win next year though ... we still need to progress with home renovations ... eventually. And pin prices keep going up.
