I use the 5.11 Rush 72 pack (about $150), and can speak of the quality of the 5.11 packs. Offering this info so you can consider one of the less expensive packs 5.11 offers.
However, the best bang for the buck I've come across is the LA Police Gear Operator Backpack for $44.99. Its huge at 2920 cubic inches, great quality for the price, and tan version they have is the best looking tan I've seen so far.
This is the pack my son has for camping, hiking, and go bag.
