Scott, ring up gardiner pole systems and ask them to give you the best price they can for a Gardiner backpack and 25clx pole, I assure you, you will be happier, the more I look at that pole the more I want to warn you to stay away! The gardiner website is being updated at the mo, but you can still ring them for advice,
This will get you going then you can work your way up to a full system, you can buy your pure water from someone locally and save on the reverse osmosis system. You can trad clean most things and then use the back pack or even a trolley system for higher stuff, also check the polarbrite website out for there trolley systems, they are very well
Made and a good price - £240 they may throw in a pole as well, give them a call mate.
