I have become a huge fan over the years of Lowepro bags.
I have a nova 3 for my digital SLR and I just picked up a Vertex 300AW to be my new taping bag. I wanted something that could carry all of my gear (TL's, V3, cables, mounts, windscreens, bats, everything along with my camera) along with a laptop if needed. This bag is sick....everything fits perfectly, it has water resistance zippers and a pull over rain jacket when needed. Fits a 17" laptop to boot and even has special easy access pockets specifically for flash cards (hello mircotrack!!) It has an 8 point harnerss with mid and lower back wrap arounds and is super padded. I love this because most bags kill my back after carrying them for a short period, end up triggering wicked tension headaches if I lug gear too far improperly and then spend 20 minutes stoopd over setting it up. Litterally knocked myself out of a few shows starting bad headaches in this manor. I can walk miles with 40 pounds of gear with this bag with no discomfort.
I also love the sonicase if you are using gear best designed for it, no bag is easier when it comes to being able to set your stuff up and not have to move it at all out of the bag. Portabrace makes some nice bags, but I find them to be a bit pricey.
