I said that once... "Go back get the camera's and sell them". I am guessing it would cost More than 12 Billion to collect all 12. I have little doubt they they would still work... that is if they had batteries.
BTW... I met and to some extent know Armstong and Cernan. I have no doubt that we went to the moon. I personally have heard Cernan address the doubter's his conviction is the same as a father defending his daughter's honor.
If we had "faked" going to the moon... would we have done so good of job?! That's my opinion.
