Any of the Sci-Fi series would be nice, Space Patrol, Tom Corbett: Space Cadet, and other that only ran 26 episodes was Captain Zero, which has been dropped onto fair to so-so dvd sets. Network did a very nice BD collection for the UKs puppet series, also given the name "Space Patrol", although has nothing to do with the US series of the same name. Occasionally another kids series arises Johnny Jupiter, again live and puppet show, very common for the era (Howdy Doody and the Paul Winchell Show). But not really sure how many of those epeisodes still exsist?
