It's unfortunate there is just no good copies of the 1997 SE anywhere. The Flunk version is about the best there is for ANH, while still having problems. ESB and ROTJ, seem to be even worse due to few sources.
Shame really, ESB deserves better really. The 1997 SE version is my favourite version of them all, and there just isn't a source available that does the PQ and AQ justice, so I can totally understand why d_j wants to mix and match sources for all of them.
