I bought some of the individual mylar sleeves I saw mentioned in this thread:

I then put the sleeved cards in standard 9-pocket pages, since I'm super-paranoid about trying to get the cards into and out of 15-pocket pages (some of my cards are fairly rough and could fall apart if not handled very delicately). I've been very happy with this set-up.
Leon, I hope the re-post of this is acceptable. If not, my apologies.
