If it was 2000 you could probably sell that guy for $40000. Unfortunately, in 2013, I think you're looking around the $1000 to $1500 range. Depending on any modifications to it and add-ons (lift, screen, etc.) you might be able to sell it for $2000 to $2500. I've seen some listed between $1500 to $2250 - even seen one listed at $5000!
I have a Vision One that I received in a home purchase - knowing nothing about CRT projectors I figured it was either useless or comparable to the local cinema. I was half right. It is definitely a top of the line projector that still competes with new digital projectors. Unfortunately, they are hassle to maintain and expensive to upkeep.
I have no idea about the Faroudja - I have one too, but I do not know what it is worth. I'll probably sell mine in combo with a Lexicon MD-12 (non-HD) pre-amp I have.
I'll give you the same advice that was given to me: enjoy it until you need to fix it. Good luck!
