Nice working Fathom for $500 back in the mid 90's
TAF IPB playfield for $250 I think, sometime around 2000
CPR EBD playfield
CPR limited edition white Centaur playfield
Genesis $400 about 3 years ago
Nice Stern Dragonfist project for $350. At least I directed it to a good home
I regret not checking CL everyday and missing a project Star Gazer for $450 by a couple of days
Complete BK head with backglass for $10. I bought his playfield to use for coffee table. Found an empty cabinet years later, so I could have had a complete machine for less than $100

Cool game, got to play one for the first time recently.
