I bought the DVDs to Classic Who episodes "The Deadly Assassin" and "The Invasion of Time" a few weeks ago and was amazed at how well they hold up. BBC could create some incredible sets with $0 budgets (All visuals FX are wince inducing though). Granted Tom Baker was the first Doctor I experienced so I'm biased, but damn if he still doesn't rock the TARDIS as well as if not better than anyone else.
