What about old Insteon devices?

I still really like my Insteon switches, outlets, etc. I will continue to run them with HA until they die. But I was wondering about people that are ditching the Insteon products for other manufacturers. What are you doing with the old devices. Tossing them out? I wouldn’t mind having them as backups if they are going to be tossed. Don’t know how to potentially pay for them or get them shipped without getting scammed. I’ve already seen that someone on Amazon is trying to screw someone by selling the dimmer switch for more than 5 times what I paid for most of mine.
