I had a similar experience with getting a Creature, was told the hologram was missing and priced appropriately and that it didn't affect the game play. I agree it doesn't affect the game play but once I created the hologram alternative it enhanced the game but in a way that I got 2 buzzes out of it. One when I got it and another when I upgraded it. As long as the price is fair and in time there is that stoked feeling of finding the parts and getting it running to a point of what it is meant to do is a great reward and I think you can even value it more.
I also agree with Brett from the perspective of a newbie that hasn't done any research and buy's it, but as long as they get it for a good price they will be stoked to upgrade it and enjoy to former glory.
