I actually thought they were worth getting. Sure it doesn't amount up to the majority of the fan edits around here, but still i think its worth it. My opinion of course.
I do think the sound in some of the dvd's, (Not ROTS) was better and i thought the picture was better in them too. Still not a big improvement. The thing that irritates me is that the ESB still has the blue freakin' tint in it.
So, not a big improvement but better.
