There's currently a sale on on the Photon website
(here) (ends June 30) and it works out cheaper to buy one from there in the States and have it shipped across the pond (Air Mail = $4.40). Penrith Survival Equipment
(here) also stock a single Photon model which I think is the PII - they don't label it as a particular model - and it retails at £12.95, like HH.
