Go to WALMART, there is a DVD set of the first season from 1964! It was only $20 about 3 months ago!
It was awsome, the color was computer restored, there is some of the editing they did in the early 70's: in the episode, PURSUIT OF THE PO HO, Race paints himself purple to look like a water god, tries to warn Dr Quest he is about to be rescued, he shouts out from the river, "HEY YOU FILTHY SAVAGES!"
I remember that from watching it every Saturday, only one day, they showed it, and that line was edited out!
It is edited out on the DVD set, too.
