Check out www.rokslide.com. Plenty of packs out there less than the Kifarus, which are fine packs for sure. Exo Hunting and Stone Glacier are two brands starting to gain tractions.

If you're a vet or LEO, you can sign up on Promotive.com and get a very nice discount on Slumberjack and Eberlestock.
