Quoted from Skulz:Main post and title edited. Found a Medusa and having a FG refurbished.
Still looking for Star Gazer, Catacomb, Xenon, Bride of Pinbot all 100% working and collector quality.
Machines do not need to be 100% original.
This is just f.y.i.: I'm pretty sure I saw a Catacomb up on eBay, within the last 3 - 4 weeks. (I had never heard of this table, prior to that.) Don't recall the condition, but it was listed as extremely rare, with a price to match.
Saw a Star Gazer -- for the first time -- at INDISC 2014 in San Dimas (though not in the main tournament) which seemed to be in VG+ condition. A collector / player I met there also mentioned having one in his collection. I tend to doubt that either owner would be inclined to sell, but don't really know.
Would welcome the chance to see and play a Medusa -- I've only seen photos. Xenon and Machine Bride of Pinbot are not terribly hard to find, though condition will vary.
