User Review: Katadyn Pocket
Price Paid: $265
If you go on long trips, don't leave home without this. I used mine in Maine after my GPS went down. I was alone for almost two weeks, and ran out of fresh water on the second day. This effortlessly filtered my water from the local streams (which I was told was parasite-ridden during the summer months) for over a week. Very handy, I never got ill.
