Ebay would be a good place to start, I think. All of those three games were very popular, so there should be lots of copies out there. I only got the talkie version of Fate of Atlantis for a very fair price about a month ago. :Brain:
I doubt you're going to find an original release of the first Indiana Jones game on a CD, though.
Edit: By the way, why aren't the first two Monkey Island games on your list? Already got them?
