If you're taking recommendations on non-self-contained trades now, too -- like Sandman -- this is a must-read. Make sure to read at least the first two before you decide if you like it: Gaiman didn't find his "voice" for the series until the second book (not that the first isn't good, it's just very different). Book four, Season of Mists, is my favorite story arc in any comic book, ever.
In that vein, as others have said, Preacher also rocks on toast.

If you like manga (or want to give it a try!) , Katsuhiro Otomo's Akira series is a classic (6 big books), and the Lone Wolf and Cub books are phenomenal (28 of them!). I quite enjoyed Uzumaki (3 books), which has some truly horrific imagery, and Nausicaa (4 books) is unbelievably good.
In the realm of Batman stories, I'll second No Man's Land (5 books, or 6 with the prequel), and I can't believe I forgot The Killing Joke (Alan Moore) -- it's tiny, self-contained, and very dark indeed. Also, Long Halloween is very good, a quintessential Batman story; the follow-up, Dark Victory, feels to much like a re-hash, but it's pretty good as well.
