I've had my eye on this bag - not to buy one, but because until seeing Andy's pics, I thought it was constructed EXACTLY like the "Sabastio's Reporter Satchel". I have the A&A bag, and these are the differences I can see:
The A&A bag is made of three different materials: heavy cotton, ballistic nylon, and real leather. It appears that the copied version of this bag is made primarily of a lighter weight nylon. and is not going to hold up as well over time. BTW,there is absolutely NO vinyl on the Sabastio bag. The front flap is all leather, including the edging material.
The other important feature of the A&A bag is that it has an adjustable plastic snap-buckle that allows you to secure the contents of the middle pocket to keep any large objects from falling out. This is where I keep my camera, although it should also be able to keep a lens from falling out too.
The copied version certainly looks like it's worth the money, especially when you consider the price of the Sabastio bag. Fortunately, I got mine before the price increase this past year.
