Space: 1999 (30th Anniversary Edition Megaset) (1975) for $41.49

When it was first broadcast in 1975, there had never been a more lavishly produced science fiction TV series than Space: 1999, a British production whose budget for the first of its two seasons ran an astounding £3.25 million. What keeps us fans enthralled after all these years has only partly to due with the first-rate production values, the plausibly constructed spaceship models, and expert special effects.
