As far as I am concerned, I own :
- the original RCA-Victor 2 CD Releases from 1997 for A New Hope, Empire Strikes Back, Return of the Jedi. Would love to have a scaner here to show the booklets included, the 2004 Sony re-issue is a shamed compared to those gems.
- the Sony releases for the 3 prequel movies
- a re-recording conducted by John Wiliams of material from the original trilogy: Amazon.com: John Williams Conducts John Williams: Music (

I used to have the 2-CD set from the Phantom Menace but I trashed it, I would highly recommend against it, poor editing, very few unreleased material in there.
