Skunk I have the Adventurer Opti and like it alot. Its small and fits into the opening of my Klean Kanteen 40 wide-mouth. It uses the same CR123 batteries that I use in my flashlights so minimizes spares. If needed I can pull a battery out of something else also. The MSRP is about $90. They also make a solar recharge case but that pair goes $150. If you have another way to charge batteries then it is unecessary.

On to more important matters (besides food). WATER!

Ok. I figure the water filter is not that hard to figure out,a Katadyn hiker or one similar. The Steripen is what is driving me nuts! Which one to get. I've found them from $44.00 all the way to $170.00 for the solar rechargeable one. If Bill Gates was my uncle I know which one I would have! But he's not even close to my family grapevine, so.... I'm just looking for one for emergency use. I figure if the folks up at the old home place can still drink out of a spring without getting sick it should be good in the event of an earthquake if the New Madrid fault decides to cut loose. I figure we could walk the 12-15 miles IF NEEDED, but hopefully we would be able to drive up to the hills.
