I'd definitely recommend classic Who, both these early ones and the later, completely-existing ones.
The following web site list all Doctor Who Classic Episodes available on DVD and probably has a list of the new episodes also if you look around. Hulu Plus currently has all Classic Doctor who episode which have been released to DVD in the US. ,Watch what you say about entirety, the last episodes(web of fear, the enemy of the world, etc.) released on DVD have new cartoon footage to replace missing sections of the original film footage. The Classic Episodes only have one story per DVD so the DVD list shows every story. For the new series, the DVD list is probably not very helpful and you may want to consult the episode guide.
This is a link on the following website to a webpage with pictures of the DVD covers and episode names for all Doctor Who Classic DVD available in the UK.

I believe there are original DVDs/Blurays of the classic Dr Who----either Ebay.com (DVD/Blu ray sect) or Amazon.com.
There is a fair amount of Classic Who on Dailymotion.
Since Google won't tell me and I don't want to look through wikipedia for hours I was wondering which of the old Doctor Who serials you can watch in their entirety.
