I've just bought this DVD set (although it has yet to arrive) and I was wondering if there's anything on TR-47's 7 disc set that's worth paying the extra $15 for that I don't get with this one.

Here's a complete list, but I don't know for sure what's what.

Can you help me?

Here's TR-47's set:

Disc 1 - Star Wars Bonus Material:
-The Making of Star Wars (1977) 50 min.
-SW trailers
-"The Moments We'll Always Remember" (30 sec. The Simpsons promo featuring Bart blowing up the Death Star)
-2 deleted scenes
-Alternate Cantina scene
-3 original audition clips from 1975 featuring Mark Hamill, Carrie Fisher, and Harrison Ford
-Carrie Fisher as Princess Leia on SNL clip (1978)
-TROOPS (featuring the original "Bad Boys" theme that is not on the Total Movie DVD)
-"That 70's Show" Star Wars episode

Disc 2 - The Empire Strikes Back Bonus Material:
-SP FX: The Empire Strikes Back (1980) 50 min.
-TESB trailers
-Harrison Ford, Anthony Daniels, Carrie Fisher, and Billie Dee Williams interviews from 1980
-Underoos TV Commercial featuring Boba Fett 30 sec.
-THX demonstration short, "WOW!"
-THX sound editing demonstration short, "Soundtrack!"

Disc 3 - Return of the Jedi Bonus Material:
-Classic Creatures: Return of the Jedi (1983) 50 min.
-From Star Wars to Jedi: The Making of a Saga (1983) 65 min.
-ROTJ Trailers (including "Revenge of the Jedi")

Is it worth getting ontop of this "Forgotten Scenes" set, or should I save myself $15?

Thanks for any advice!!
