I usually use the shit out of stuff I buy. I think hot tubs are often a bad value for people, though. I have had 2 hot tubs in my life. First one was a used 110 plug hot tub I bought for a hundred bucks about 12 years ago - it actually worked damn well for a 110 unit - and was full sized, not some small thing. I used it for about 4 years before it died to the point that it wasn't worth to fix (which I had replaced the heating element once already). Then about 3 or 4 years ago, I bought a slighted used Hot Springs hot tub, a 9K hot tub only a couple years old, for $1500. It was nice. But we were gone for a week in January that year, and our power goes out at our house in MT often in the winter (we live in the mountains and are on a pretty rural power line setup which goes down often in the winter), little did we know the power went out during a 5 day sub-zero stint. Froze the hot tub solid since we had no power and it didn't get above zero for days, of course creating a bunch of leaks since it froze and it sits outside. I have yet to fix it, probably never will.
I have had a full home gym for years. Some of the stuff I picked up dirt cheap (or even free for some items) used. Or not even used, a couple items never unboxed. I also bought some good value stuff online. I would much rather work out at home - and it is pretty much a full gym although one does need to supplement some, like I don't have (or want) a hip sled for instance, but I do have a smith machine as an example - but it is 1000% better to be able to do it at home than go to a gym. Hell, we barely even have a gym here now, the main local gym shut down out of the blue a year ago - just closed up overnight one night with zero warning to customers - the owner was into some shady stuff and had to shut down about 4 gyms here in MT he owned. But for the money I spent on my home gym stuff, absolutely over the years a great value.
I have never owned a boat. I am on my 2nd 15' white water raft - first one bought about 20 years ago, and it needed replacing, but was used many, many times. Bought a new one last May, took it on an amazing 6 day back country float trip on the Smith river here in MT in late May last year. Haven't used it since, though. Need to work on that this summer. Rafting is one of my favorite things I do here.
