Have you seen the documentary American Moon? It's rather long winded but covers the technical aspects of the filming rather succinctly.

Given the technology and resources of the time, and having the luxury of examining the historical record of the events I'm hard-pressed to believe they made it anywhere with the technology advertised.

I've heard the "we made it, but couldn't disclose what we saw" argument before, but it just seems like an easy deflection from the heaps of information suggesting the US faked the entire ordeal.
