I've seen every single Halloween movie on TV, With the exception of the first one which I own on DVD. My question is ( and this applies to part 1 as well), what are the best DVD's to buy for each and every Halloween movie ( with the exception of Halloween 3 and 8, which were unwatchable). Which are the bests that included deleted scenes, bonus features, etc, for Halloween 1, 2, 4, 5, 6, and H20?

Help would be appreciated, as well as link to the coverS of each DVD.
