That's the one!
I remember it well (unfortunately) and found it seriously creepy. Those reborn dolls, as they were called, looked like dead babies...it was like something out of a horror film. I couldn't and still can't understand how anyone could find any comfort in one of those things. I wouldn't be able to sleep in the same house as one.
While I'm sure the production team went out of their way to portray those who collect these dolls as loopy as possible to make for an entertaining programme, I do think at least some of them had to be genuinely mentally unstable.
The whole thing was just flat out WEIRD - especially the lady who made the dolls and said that though she suspected some who bought them could be peadophiles (or, at least, it was implied I think when she was asked, even if not stated in so many worRAB), it wasn't any of her business. She was obviously laughing at the poor saps who bought her product all the way to the bank.
