Ok I bit the bullet and went ahead to buy the Domke bag, model F-3X, in black.
I like the spaciousness of it all plus the fact that there're in total, 9 compartments: 1 in front, under the flap, 1 as part of the flap, 2 on either side where the straps connect to the bag, 1 main compartment split in 2 by a removable divider and 2 circular ones which I guess would fit a pair of TC & WC lenses nicely.
The central divider in the main compartment is a little short but that's simply because it's meant to connect to the 2 inner circular compartments via the centre. I am not sure if Domke carries a slightly longer one but this one seems fine for now with some arranging here and there.
Another thing I like is the fact that the back of the bag isn't padded, which translates to a softer overall bag(I kindda prefer softer bags anyway) and since the camera is placed sortta diagonally, with the LCD turned inwards in storage, that works fine for me.
You can store the camera with or without the supplied lens hood. I am keeping mine on for now.
Space is a little tight it seems but it isn't that bad as the 2 side pockets have ample room for a spare battery + charger and a complete cleaning kit or filters if you so desire. Also, you can purchase extra pouches to sling on the main strap if you want to but for now, this works for me. Throwing in an external hotshoe flash should not be a problem as well.
All in, a good compact bag for 1 or even 2 SLRs, I probably will be using this alot more than my Billingham which I find too big for my present digital camera needs.
