I have some pretty good copies (s-vhs) of the SciFi episodes. The only problem being that they are edited and have a watermark. At least a good minute or two from each episode is cut in those versions. Shame really. But to be honest it cuts out a lot of the slapstick nonsense from the episodes and can make them more watchable.
I have a copy of the original ABC airing of Coby that is decent. I am in the process again of performing an IVTC and slight cleanup with some updated tools.
Hopefully in the next few weeks I should have a torrent up with a majority of the episodes done.
