When it comes to DVDs, Criterion is pretty unfuckwithable--no other company seems to care quite as much about the films they release as Criterion does, and they always do an incredible job when assembling their releases, regardless of whether the auteur behind the film is Bergman or Bay. (My personal favorites out of the Criterion releases are Rushmore, the Beastie Boys Video Anthology, and Rebel Samurai: Sixties Swordplay Classics.)
And Criterion's now even better: They've just launched an "online cinematheque*," where you can rent selected Criterion releases for $5, watch said film as many times as you want during a week, and then--if you decide to buy the film--apply that $5 to the cost of the film's purchase. Not a bad deal at all if you're on the fence about picking up one of the film's they've currently got available for rent. And since they promise more films will be added to the virtual cinematheque, this could turn into a really great resource for watching hard-to-find films.

*"Cinematheque" is pretentious movie snob-ese for "movie theater."
