I've used a LL Bean Classic since high school... yeah, it was an early model. Still holding up, even after being pressed into BOB and camping duties for a while.
I had the Blackhawk version of the Eagle Becker pack, made before they moved thier prod overseas. Decent, but the pockets were smaller than I wanted. Still a fine pack, but I'd recommend the Eagle version of it right now, BHI's reputation isn't what it was even a few years ago.
I looked at the Tactical Tailor Three Day Plus, almost went with it. I own quite a bit of thier gear, two thumbs up on all of it, so I can't imagine that their pack isn't just as good.
What I have now is the SpecOps THE Pack. Very well designed, very rugged. My only real grumble is the design of the waist belt but it's easily enough removed and replaced with something a little more capable when I want or need a waist belt.
All of these are in your size range, and all but the Bean pack are hydration compatible if you really feel the need. But the Bean is the only one under a $150.
