I've been using the life systems drops for a while now, no foul taste, but a bit of a pain though as you have to mix the drops, wait 10 min, stick em in the water, wait 30min more.
I ended up walking into an outdoors shop today at lunch - lo and behold they have a sale! SteriPen Adventurer was on clearance, so I ended up with one of them after all. Will have to report back on how it goes.

Anyone had any experience with water sterilisation? Mainly looking at steripen, as the tablets leave a foul taste. http://www.steripen.com/compare/
Water source will be food grade rain water tanks.
