There's a fair few releases in my DVD collection i've paid a fortune for and the most expensive if i recall rightly must be the following:
Grindhouse (Japanese edition £70)
Spider Man (French wooden crate set £150 and the Japanese gift set £60.)
Spider Man 2 &
3 (Japanese gift sets £60 each.)
Death Wish 1 -
5 (Australian 'Vigilante Collection' edition £150)
The above prices are to the best of my knowledge correct and there's more titles to come in later posts. I just have to note 'em down first!
