Spire USA (Score 2, Informative)

I would suggest http://www.spireusa.com/ I bought a backpack from them about 2 years ago and used it to carry my dell 8100 (a brick!) as well as some school books (bricks also). I figured the weight would cause the pack to break but it help up quite well. Also some of their cases have what they call a boot that the laptop goes into the give it added protection. HIGHLY RECOMMENDED.
