Just got the complete Dr. Who "The Key To Time" adventure from Amazon on DVDs. Personally, I'm a Peter Davidson fan more than a Baker fan, but he is the archetype. And there's only a handful of Davidson episodes out so far. . .
I do so want a sonic screwdriver.

While I appreciate Peter Davidson (certainly a damn sight better than the horrid Colin Baker), I must confess that Tom will always be the Doctor in my mind, and Peter will always be the Dish of the Day from the BBC's wonderful Hitchhiker's adaptation. ...
I think it's really Nyssa that is the reason I'm a Davidson fan.
