Many months ago I put a post up about a camera bag that could hold my gear, and my laptop. Well picked up a Cyberpack 8 and it almost..just almost worked.
My laptop barely doesn't fit, but it's still almost passable, here's a picture with a bunch of gear in it.
I have some extra stuff in there because of work, but if I wanted to could fit both cameras, and pretty much all my lenses in there. It's a nice and huge bag, and at the price (169 shipped) worth it
