I was too young to see it in the theater originally (I was 3) so I didn't get to see the originals on the big screen until the Special Editions came out. It was still worth seeing it, but I wish I could find a screening of the unedited versions somewhere (actually, I'm disappointed they didn't re-release the original Indy movies in the theater before Crystal Skull came out).
If I were to compile my own "ideal cut" of the Original Trilogy, it would just be the THX remastered version of the original, (the last release on VHS prior to the Special Edition) but reinserting the scenes of Jabba and Biggs in ANH, and I MIGHT use the DVD edition of the conversation between Vader and the Emperor in ESB (the dialog in the scene actually DOES date to the original script, and IIRC it appears in the original novelization).
