Dark Jedi's ROTJ V3 GOUT is quite nice, imo it came out best of the three. I think mainly due to ROTJ GOUT being a better transfer than SW, or ESB.

Part of the reason for what you perceive as a lack of attention is that there are already good ROTJ restorations out there, that and maybe the fact it is widely felt by most SW aficionado's to be the weakest of the trilogy?

Oh, and who cares about the 97 special editions, lol :P

I can understand some younger peoples fondness for them though, as that may be how they were originally exposed to SW? As an older guy who saw SW in the theater and the drive-in I personally don't have much love for the special editions.
