It's on DVD!
For those of you that care enough to visit this message board, Space Rangers has been released on DVD in Region 4 in a two disc set. The cover artwork is crap and the transfer ain't great, but hey, you've got all 6 episodes preserved on DVD!
Just do a bit of surfing at sites like EzyDVD, Atlantic DVD and other R4 sites and you should find a good enough price.
Cheers!
