The only times I really think about their cumulative value is when every single visitor unfamiliar with the hobby drills me about their value and look at me like I’m nuts, and when we get our monthly “once a decade” torrential downpour and I have nightmares that my insurance company tells me that my agent forgot to renew the rider on my homeowners insurance. But yeah I’ve built a pretty great stereo/vinyl setup over the last 20 years that, while not cheap, gives me waaaay more enjoyment for the buck than pinball. The audio gear being underwater is also part of the nightmare btw.
