Also, there are several projects now working to preserve the 1997 SEs.
Dark_Jedi is making a DVD set from the digital broadcasts and the laserdisc 5.1 mixes, which will probably be the highest-quality version available.
Another member is also working to capture the PAL laserdiscs of the 1997 SEs, and I believe another is working on the NTSC laserdiscs.
So in the near future, the 1997 SEs will be more widely available than they have been since ... well, before 2004.
