Hey man, you have a pretty solid collection. I dont know if you are a freak about picture quality (anamorphic vs. non-anamorphic and whatnot).
But if you are, you should consider upgrading:

12 Monkeys (the new edition is anamorphic and has an INCREDIBLE full-length documentary and commentary)
The Big Lebowski (the new collectors edition has a vastly improved image quality. However, it doesnt really have any extra bonus features)
Jaws (the new 30th anniv. Edition has the original mono track and the full-length documentary from the laserdisc.....not the sub-par and heavily edited version on this release)

Also...you seem to be into Wes Anderson's films AND Criterion releases....
Please, if you ever get Rushmore, buy the Criterion edition. The image quality is AMAZING and the bonus features are great. Especially the shorts.
