Went to a local army surplus store looking for prices on used ALICE packs, hoping that they might be cheap. No luck. THe ones with the frames were around $70; the ones without didn't have prices on, and I didn't bother to ask. I can get them for $20 or less on Amazon or Ebay, so maybe I'll do that. Just looking for a good, cheap bag to hold a bunch of stuff, with a little bit of organization. I like the ALICE / MOLLE packs, as well as the USMC ILBE Assault packs which may also be an option based on how much I end up having to spend. I'm honestly not sure how much cargo capacity I'm going to need for a proper BOB, though being able to include a bedroll, wool blanket, and tent in addition to everything else would be a nice bonus. I kind of really like the MOLLE pack I saw tonight, with a zip-together divider that turns the main compartment into two compartments, with access through the bottom half of the front. Unfortunately they wanted something like $150 for it, which isn't happening. So, anyone have any great rucksack secrets that might help me find something good?
