Actually, I think I stand corrected. I just googled them and I think I was thinking of the original "Dexter" from Perfect Match, although I believe they also have The Robot of some description. I should probably call in there some time...
I have the complete DVD set and they have the original version shown to the TV executives and there WAS no Smith! Some how it lacked something...personally, I would have left him behind the first time they took off, if I hadn't pushed him out an airlock before then
