I do collect the versions he has put out so far and enjoy maintaining this collection each time he releases new changes. While I do think that it would be nice if Lucas could keep up all of the various versions in high quality, I'm still going to be able to enjoy the previous versions on Laserdisc and VHS (and now non anamorpic DVD).
I am just lucky in that I think that overall Lucas' changes have improved the film even if not all changes were for the better.
