That's a weird thread.  Dies in 2004?  I can only assume that if he were selling stolen property, something would have come of it.  But these Robotrons, as far as I was able to tell, came from an operation here in the states that went bankrupt a couple years ago.  I was searching for a Robotron, came across their old site, and they had a pointer which said John's had purchased the remaining units.
Also, he's been so totally stand-up: fixing the little blemishes with expert workmanship, testing the unit, replacing the IC, communication, multiple pics from every step of the way, not really the behavior of a scam artist.
The machine arrived at the airport today, so I'm off to get it this evening.  Pics and maybe video soon to follow.
