I'd prefer to make more than one vote. I think the late SS (SYS 11), dmd, modern dmd will be strong on value. LCD should be, but time will tell. Theme may also play into this as people's tastes for nostalgia evolve as well. My layout is from 1985 to 2021, my 5 yr old likes them all, so there is hope for future pin heads out there.. This week I started explaining some repairs to him, not sure he got it all, but he did pay attention.
