I have used this system on a number of international deployments, REALLY the slickest system around IMO.
Complete, new in box Hydrowell2 Expedition Water Purification System. This is the complete kit, listed at the link below with all accessories and needed parts included. It has everything you need to take it out of the box and bring it on your next trip, plus a few extra goodies like 20 syrup pouches
Retail for JUST the Hydrowell2 bottles is about 375 (say, from amazon) without the full kit.
400+ shipping get everything.
