has been asked, but i haven't seen any threads that answer the question enough for me to make a decision. As it stands, the last piece of gear I feel I need is a water filtration device. I spent over an hour at Cabela's today speaking with a seasoned gentleman that claims to have completed the AT in sections - therefore validating (in my mind) his ability to advise on filters. He recommended a Camelbak sterilization bottle over the various Katahdin options. I walked in the door looking to purchase the Platypus Gravity Works 4.0 filter system because I AM LAZY and I really like the idea of not having to pump my water. However, after speaking to the Cabelas worker, I was more confused than when I walked in.

So I pose the question - without spending $300 on a filter system, what are the options to consider and which systems do you recommend the most?

SIDE NOTE: I will be using this filter on multi-day hiking and kayaking trips.
