I've got the 18 aired episodes on 4 dvds (always interested in hearing about higher quality versions), but I don't have the 4 unaired episodes. They did air somewhere, so I figure someone has them. Here is the list:

19. She's gotta have it
20. Dog gone
21. The Psychic
22. The Big Finish

Email or PM me if you've got them.

Thanks!

Kevin
