Ady's ESB is about as close as you can get, but it isn't quite the same. There is the Reivax version for ANH-it's from a Beta tape and looks great, but unfortunately is in PAL format and only has a 2.0 track.
Laserdisc captures can be good, but there aren't any out currently and all will have the pink tint form the telecine. The best would be the G'kar, TB, or another broadcast version. Sadly, there aren't any now. I hope someone does finish a 97SE set with the full 5.1.
