I have had 3 Dr. Whos that all got away. The one that really bugged me was a game that was totally working and then when you got to the Davros JP sequence... the gray targets on the time expander would all register but one. Totally frustrating. Both myself and my fixer COULD NOT figure this issue out. I sold it at a loss to another collector who when through the whole game with a multimeter and found a single diode on the target that would not register that was installed backwards.

DAMN.

But I have to give him credit for being more thorough than I was and he got the job done.

The second was a game that ended up being part of another trade with a third party. He just plain wanted it more than I did.

The third was a game that I agreed on a price with for the seller, I gave him most of the $$$ and went to the bank to get the rest. His roommate convinced him to sell it out from under me. He gave me all my $$$ back, but I'll never trust either of them again.

Some day...
