I have the Kata DR467i as my traveling backpack. It takes the T1i with the 24-105 mounted, plus four other lenses all in the lower compartment. The upper compartment carries chargers, batteries, cables, cards, and maybe one small lens. It also has a backpack compartment. It's heavy carrying all the stuff, but I've fit it easily under the seat on even small airplanes. I also have a smaller Sling 102 for just the T1i with a lens and maybe one or two other lenses for walking around. Then I recently bought a Kata Large Reporter bag, which holds everything nicely, for the car. My day to day camera hauling is in the car and the Reporter bag sits flat on the floor and has a very easy access to the main compartment through an central zipper. It's not something I'd carry around on a walking tour, though.
