Like I said, this isn't *as* important as SW, because we actually have an ESB source with good color. It doesn't look like anyone's biting, so we may be able to wait until someone does have sufficient money to fork over.
As to the documentaries, I have no idea, I'm not a film collector and I don't actually frequent the 8mm Forum.
I'll keep my eyes peeled on eBay, maybe those will turn up in the future. Fortunately, I believe both would have been on LPP...
