I've used Deuter rucksacks in the past and they have lived up to their reputation of being built like a tank but of being anything but lightweight. I know they have a more varied range now, and if you find a model you like I'd have thought they were a safe enough buy.
Ive been using Deuter bags for years now, mainly the Guide 45 and guide 35, both have been great hardwearing packs, they also do awomens version that may be worth you looking at
