Here's what I own of SW on DVD:

The 04 Set.

A set from here of the Laserdisc collector's edition(which I own too)

That's it.

I also have the original separate releases of each prequel.

And I wont be buying anything more until Lucas stops this love/hate thing he has with his audience and releases a mega box set of original theatrical versions, NO FIXES, and whatever else he wants to put on it.

I used to have a list of stuff I'd want for a mega box set but it's obvious Lucasfilm has lost touch so why bother?
