Sorry but this is not 100% accurate: I own three of these superb machines (2 halogens and 1 Xenon) and whilst they are real workhorses, they will probably have glitches, malfunctions or even worse after many years of non usage: that's pretty normal, for electronics 25+ years old. I had the chance to see a dedicated and skilled technician work on these projectors and believe me the amount of dedication it takes him to explore every possible source of troubles, is really astonishing. Every elctronic board is removed from the machine, checked, (soldering points) cleaned and reassembled. The same applies for the countless microswitches, solenoids, relais etc. Often they have to be cleaned or replaced. Also this projector is ill-known among S/8 enthusiasts for its 'partiality' in scratching films, if some parts which tend to wear, are not modified accordingly.
All that said I think € 400 is nowhere close even to purchasing a standard version, let alone a Xenon.
