The esteemed company known as "The Criterion Collection" is a savior to film buffs like me.
They clean up original negatives & sound, (usually with director approval), add some killer features depending on title, and package them just like I would if I ran the co. I'm sure some people on these boards are aware of this wonderful institution and probably even have some titles at home. They can be pricy-especially here in Canada with our dollar worth 60 cents to the US greenback, but some DVD's you MUST own. Mine:

...And God Created Woman
Andrei Rublev
Grand Illusion
Eisenstein:The Sound Years
Spartacus
The Royal Tenenbaums
The Seventh Seal
Wild Strawberries
The Last Temptation of Christ
The 39 Steps
Amarcord
The Naked Kiss
Rashomon
Kurosawa "samurai" box set (just bought)
Solaris (just bought)
Monterey Pop (just bought)

and there are about 15 others I am dying to buy...
