You're sort of talking early 80s pins there I guess. So discounting Sys11 (86 upwards...)
Bally Black Pyramid is cool
Centaur and Fathom you mentioned
I like Future Spa and Paragon but they're late 70s
Solar Fire, Jungle Lord, Pharoah, Black Knight are all cool
So many cool pins from that era ... And with the exeption of Centaur and Fathom, most are sub $1200.
Good times!
