I just came from a store with a whole bunch of classic Doctor Who DVDs which is currently having a buy 2, get 1 free deal. I already picked up 6 stories in this deal ("The Sensorites," "The Ark," "The Gunfighters," "The Dominators," "Terror of the Autons," & "The Deadly Assassin"). I'm now looking to pick up 3 more. The ones that really caught my attention were: "The War Machines," "The Daemons," "Day of the Daleks," "The Mutants," "The Three Doctors," "Invasion of the Dinosaurs," "The Talons of Weng-Chiang," & "Resurrection of the Daleks." Which 3 should I get?
