Digital photography

I've been using a camera bag insert for a couple of years in various bags, the one I have fits messenger bags particularly well as it's more rectangular in shape. Has a couple of dividers and lots of velcro so you can reposition stuff as you like.

However I can't remember what mine's called, but there's a few you can get!

I have had a look around for the inserts. I want to try one with my humble m3/4 set up. Camera shops in London which might stock these????

Have tried CameraWorld. They just had the Domke one. Really would like to try the Aubig for fit. Would love to get this sorted today so any suggestions very much appreciated.
