I would add myself to the "yes" column for another reason -- the box set discs represent the oringal album releases of the first two pics, and what the JEDI album should have been.
Thus it makes a nice play, and fitting partner with the score releases to the newer films.
Plus it's usually quite affordable now, so if you have the spare "change" you should pick it up.
I've had the box since about 97' - found it with a great price at TOWER. It's absolutely one of the better attempts at this whole CD box-set thing. The artwork and design are tops. The sound remains excellent.
I just put the Arista STAR WARS in for a spin again. I find that I almost NEVER play the expanded RCA 2CD sets, even though I own them all in nice, "book cover" editions. It is the four Arista CD's that get played whenever I pull out these classic scores (although not so much the fourth "outtakes" disc).
