I went to amazon site to do a search on this show and see if it might be on dvd. sorry only on vhs and though only 14 episodes, i'm assuming the one for $129.75 is new and other cost $97.51 is used but doesn't say if either one is new or used. on amazon when your looking for something on tv shows they usually show if its new or used.

I am happy to say I used to belong to this site some years back and it has the series on dvd and only cost $25. you do have to join first. I bought logan's run tv series at a good price and every thing was good on each disc. when I was looking I didn't know this. the person who had this also said it had 4 episodes that was never shown on tv cause it got canceled. so when I got it in the mail I watched them. but I don't remember if I watched the last 4 first or went through each episode at a time. I bought few more dvds on shows and each one was good quality of picture and sound.
