Probably, yeah. It seems like the newer they got the more points of failure they had. Not really sure about a year range just noticed that stuff like how the power cords used to be standard replaceable ones changed to hardwired ones. My opinion is to get one used more to save money, because if you’re just using it to cook beans or the like there isn’t too much of a benefit to getting a commercial one. If you’re really worried about making it last decades (I wouldn’t personally), then getting a non electric one probably would be preferable. I’ve seen old sears pressure canners still in use, but they do need newer seals every now and again. They just aren’t as easy to break out if you’re just making a quick meal though.

The only commercial grade pressure cookers I’ve heard of that are BIFL are the all American brand, and their electric sterilizer is very pricey but nice (came across it when I had a hyperfixation for growing mushrooms a while ago). But honestly, if you’re just using it for cooking a used instant pot or even a ninja pressure cooker will be fine. I’m partial to instant pot, because I’ve had a couple (upgraded to bigger sizes), and some of the old ones are clearly made to last a surprising amount of time (and have in my experience).
