I built one years ago. Top of the line at the time - force feedback throughout, real DMD, shaker/motor, tilt accelerometer, etc. Based on BW widebody cabinet (helpful to have a Twilight Zone sitting right outside my workshop for measurements, etc.). Right when VPX was coming out of gate.
Thought I’d use it to play FX tables. ended up using it more for rare older pins I’ll never likely own (CCr, BBB, CV, Safecracker, etc.).
That said, it rarely gets played. Even during parties when I’ll just load up TAF or Ghostbusters and have it sitting in the middle of the lineup. (The menu system is intimidating to newbies, even with Hyperpin <which is awesome>.
Love the fact that I built it (turned out pretty great; and: the story is always a good one). Requires much less maintenance than a genuine table (though: some maintenance still required; it’s got enough “pinball” in it to keep that adage true). I genuinely enjoy it when I occasionally play it. But: the joy/pride of building it is likely a strong factor in that. Not sure if feeling would hold if you buy one NIB (even a nice one, which this seems to be).
