Buy the french version from kino. It has both versions, the 25fps and the 18fps version (it's of course still 25fps but with correct timing), german titlecards, proper tinting, uncut and the original score.

A lot depends on whether you want the Stoker names (Harker) or the Murnau names (Hutter), and how much you want for extras. 

Myself, I own both the upgraded Image disc (with the reddish cover---avoid the earlier black and white one that otherwise looks identical) and the Kino because they both have strengths.  Either one will please. 


Here's what I wrote in my review of the Kino disc regarding the "longer version"

Quote:

This disc runs nearly nine minutes longer than the revised Image disc. While both seem to be running at about the same frame rate (not at sound speed, thankfully), the Kino version spends longer on the intertitles, the text of which can be lengthy. They're set in an old English type that can be difficult to read, so the extra time is appropriate for first-timers. The added footage doesn't add up to a great deal, I'm afraid. During Hutter's coach ride to the castle, there are additional insert shots (which may or may not have been done under Murnau's supervision) of landscape. As Orlok's coffins are being rafted to the ship, there is an additional shot of the raft going by. As they're being loaded onto the ship, there's an additional bit of business where we see the bill of lading and learn the ship's destination and name. The lengthiest addition comes as Ellen sits at the dunes waiting for Hutter's return. An added sequence of Harding and his sister Ruth playing croquet appears here, interrupted by the delivery of the letter from Hutter. They run to Ellen, and the action resumes as in the familiar print. Towards the end, Ellen reads at greater length in the book on vampires, making her actions in the finale a bit more clear to the viewer. Several other shots are somewhat longer as well; for instance, the famous shot of the doomed ship coming towards the camera is much longer in this edition, and there are a few additional intertitles as well as slightly different editing. Oddly, the bearings of the ship and the wind in the captain's log are different in this edition and the Image one. In this edition the original five-act structure is retained; in no other does that occur.

The additional footage adds little, really, though the logic is a bit clearer from the added segments involving Ellen. I would suspect that much of this added material was cut by Murnau himself in order to improve the pacing. However, it's certainly nice to see it here.

The only DVD version I've seen that doesn't crop the picture excessively is the one that is on a disc with the 1910 Edison Frankenstein in a limited edition---most other ones I've seen (and I've seen a lot of them) tends to cut off Orlok's head when he rises bolt upright in his coffin aboard the ship.  But it's otherwise a rather iffy transfer.  The framing on the Image disc is slightly more generous than on the Kino, though the coffin scene does have a better presentation on the Kino with a sliver of clearance above Orlok's head .  Decisions, decisions.

i have the BFI Region 2 version  5-035673-005200

the image is in really good shape. the score by bernard is also very good in that old-time hammer-esque tradition.
