Hi
Was looking for a decent laptop backpack for my new Asus 17.3" lappy and narrowed down my choices to Everki Titan and Asus ROG Nomad. Asus one is more than $100 dearer than Everki though which made the decision easier.
Has very good reviews on Amazon
The next cheapest I could find on staticice was for $127.

Vouch for Everki, i've got the Beacon and it's a nice bag. Firm, protective and stores tons of stuff! The titan is huge compared to it.
