I can't see the point of stock-piling or hoarding film just for the sake of it. I keep a good working stock of the films which I use regularly and which are still available, and have stocked-up with a few films at the time were discontinued, e.g. Ektachrome, Astia, Plus-X (all of which I used and liked). Overall, I have enough film to last me perhaps 3-4 years maximum on present usage, and tend to replenish as-and-when I see any good deals. (Just noticed that this is an ancient thread...to which I replied at the time! At least my views and habits haven't changed with age, lol.)
