yup me too, actually would prefer civvie patten but I've not seen a civvie bergen that measures up to my old issue one... If fact I may start a thread on that here in a mo. But the answer to the question is still wanted - where are you sourcing???
I got it for 35 quid including sidepockets and internal metal frame from Denbigh army surplus http://www.outdoorsurplus.co.uk/. The bergen is in great shape and delivered fast. The owner advertised six of these on ebay at a fixed price of 35 quid
