The reivax and Flunk ANH SE 97 are better quality than the Gkar version. But I still prefer the GKar, because all 3 OT movies are available.
Apparently there is another english 1997 SE from DVB source release that contains all 3 movies. It is called the "TB release".

Unfortunatly I never found these anywhere online.
I also have the original Star Wars SE VCDs from Malaysia. Quality is not very good, but If someone is interested I can upload ISOs to the newsgroup.
