I am a new owner of a Canon Rebel Xt, and will be traveling to Rome soon. Just like any other crowded tourist destination, Rome has a lot of pickpockets. I need a bag that is secure, but will also travel well with a camera - especcially in a plane as a carry on. I have been looking at buying a pacsafe Treksafe 100, then purchasing a small hardcase for the camera and lense. This will aloow me to carry extra items such as a light jacket, MP3 player, extra point 'n shoot camera for my wife, and snacks. I will carry the camera most of the time around my neck with a pacsafe slashproof camera strap, so the bag doesn't necessarily have to have quick camera access. I am also looking at the Lowepro flipside 200 which has access to the compartments from the side that is on your back. Does anyone have any suggestions on what to look at?
