Matakishi, I would recommend the Dracula with the added strings quartet background music.
The other, theatrical version, with no musical score, in my opinion, doesn't hold up well.
And, look for cheap sets of that old Universal complete sets! The bonus cds on the making of, interviews, and commentary is fantatsic! (They have a "Dracula", "Wolfman", Mummy" "Creature", and Frankentsein" and "Invisible Man" set, with all sequals (about 5 movies per set) and bonus stuff!
I picked up Frankenstein set for $8 (US), had the mummy and the Creature. The Mummy sequals are hilarfious! (How Im-Ho-Tep winds up in a Louisiana Swamp is just one funny plot hole)
