If you have a Video Recorder (and I only ask as some fowk are entirely DVD-orientated these days) I have (I think) every existing Dr Who story recorded one way or another (either official Vid, or taped off the telly). You're welcome to borrow whichever ones you fancy.

Other than the stories mentioned above, I would recommend (in no particular order of goodness)

Terror of the Zygons
Pyramids of Mars
Talons of Weng Chiang
Robots of Death
Pirate Planet
Genesis of the Daleks
City of Death
Horns of Nimon (for its awfulness)
Reveleation of the Daleks
The Green Death (thats the one that gave ME nightmares as a nipper)
The Sea Devils
Spearhead from Space
Tomb of the Cybermen
An Unearthly Child (so yoou can see where it all began)
The Daleks
