I bought a project Fathom many years ago with a repro cpr and repro backglass. Yes the cpr is super nice but i can't feel the nostalgia factor. I finally found a nice original playfield, restored it and sold the repro. Also found an original NOS backglass for big bucks, sold the repro !
I made the same for Centaur, i swap a repro playfield, few years later i found and restored an original and re-swap the playfield again
for the original, the feeling is much better
For my Fathom with all original parts (boards, plastics, display and etc), 7K+ if i ever decide to sell.
