I would want to echo what has been said before. Get the 2006 "Limited" edition. It is the official DVD release of these from LFL, and after paying LFL for those, I feel a lot better morally (even if Legally it almost certainly doesn't matter) with looking for other options.

Speaking of options, Puggo forgot to mention his Puggo Grande. It is a preservation of a few 16 mm Star Wars prints, and Puggo did a good job. It does have a bit of dirt and only the Mono sound track, but many of us first saw Star Wars in Mono theaters with dirtier (35mm) prints than this.

Also check out the work by Adywan. A year ago he released his "Theatrical Version" for ESB's 30th anniversary. Before that he released a greatly acclaimed versions of ANH that are more like what it seems most of us WISH the SE had been. Of course, this doesn't meet the need for a strictly ORIGINAL version for ANH, but you should check them out sooner or later.
