UPDATE
I recieved a written response from Joe who sold the Black Knight 2000. He had several people 100 percent wanting the machine.

The machine SOLD for $4200 (four thousand two hundred dollars) No wonder my 3300 was knocked back .lol

NOW, I AM DYING TO SEE THE RESPONSES TO THAT PRICE ! But, the bottom line is that BK2000 IS A VERY VERY HARD MACHINE TO FIND THESE DAYS. With brand new AMAZING full cabinet art now available for this machine, it now makes the machine a candidate to do a resto on and make it look like a brand new machine. That has to make the price climb. Note- I had someone offer to buy my BK2000 off me 3 months ago and they also offered $4 grand which i declined cause mine is in AMAZING condition and I have brand new full cabinet decals.

BK2000 is an amazing game that you either love or hate. So it seems the price to buy a real nice BK2000 is between $3000 and $4000. I think that is a true indication as to where the market is. To get one from pauls Germany, which was real nice, was going to be over $3500 12 months ago, and it wasnt redecalled.

The recent sale price for the BK2000 is good for BK2000 owners.  No-one will sell theirs cheap anymore ! probably.
