My DVD collection as of 10/7/2014 
Still need to get 25 more classics
The Scream of Shalka
Sarah Jane adventures series 2,3,4 and 5 
And The Tennant specials -mainly for The Next Doctor !

(edit :I’ve just looked up to see if I could get a cheap Tennant special boxset anywhere no luck -it will be like £40 :( and I only need one ep :( )
