I can give you the reviews of the bags I have, but I can't heartily recommend any of them. These decisions, for me, are greatly helped by also knowing what not to get and why.
I just got a Kata 3n1-33 (the larger version of their bags) for traveling. I kind of like it, in that it has all the pouches that I need and fast access to the camera. I dislike it in that I can't carry a reflector in it. I can also carry a laptop in it, big requirement for me. It has a strange configuration that allows for rapid access to the camera; that's cool, but the pack weighs in excess of 20 pounds when fully loaded (with laptop, flash, camera + lens, two other prime lenses, batteries, chargers, cords, cards, dp2), so no way am I carrying this around enough to warrant the extra engineering.
Before that, I had the Lowepro Stealth Reporter (no link because I can't find it on their site, but it's the notebook+backpack version). I liked that one because I could carry the reflector, but there were only three lens pouches, barely large enough to hold a 17-55mm f/2.8 lens (70-200 f/2.8? Forget it) and two camera/flash pouches. It also had a tearaway case for the laptop. The camera had to be disassembled as well, so points to the Kata for those rare moments when I have the traveling bag and need to take the shot.
Now that I've traveled with both, I give it to the Kata, but only just. I don't want to carry around a reflector on long trips, so giving it up is not a huge loss, but getting the straps to work every time is a pain.
On day to day trips, I have a lowepro topload zoom 2, and it's just a bit too small for a d300 and 17-55.
I hope that helps...
