if you've got a 16x9 -- go with Dr. Gonzo. Maybe not as sharp, but the color is more true
Either way, go with Rowman's supplemental discs. Essentially you end up making 2 disc special editions. If you wanna go 3 disc, I recommend getting Darth Editous ANH edit, and A Digital Man's ESB and ROTJ edits to complement the original versions and the bonus disc
