I have both the Domke 803 (3 of them actually) and the Safrotto clone. I am not sure what phtomoof is talking about; I have not had these problems with my Safrotto. The Safrotto has a zipper pocket inside the flap (which they must have cloned from pictures of Domkes where I had seen them, although I have never had that feature in my Domkes.) It is a nice feature. Also whereas the Domke 803 has separate zipper pockets on the front of the flap, which I like because with SD cards, I use one side for unused ones, the other for used ones), the Safrotto, while it has two zippers, they lead to one pocket. The Safrotto is also slightly bigger than the canvass 803. When I had a 12" powerbook, it slipped easily into the back pocket. The macbook will not fit in the 803; I don't know about the Safrotto.
I bought the 802, because I needed something for the macbook pro I bought to replace by dead powerbook. I was hoping it would fit in the back flap, but it doesn't. As a camera bag, I much prefer the smaller 803 to the 802.
