I have nothing against Goodwill and nothing against $120 backpacks, but I can't imagine paying $120 for any bag I would find at Goodwill.
At that price you can get a top of the line Ortleib, SealLine, TimBuk2 or Chrome bag brand new with manufacturer warranty against defects.
They are all slightly different in design philosophy so I would go try them on in person. REI would have all of those brands if there is one near you.
