I just received my Crumpler 5MDH and I love this bag, the neck strap is nice and thick, and the bag overall if very sturdy and supportive (I feel like I can swing it around and not worry about the protection of my D7000).
It has a nice zipper mesh compartment on the flap and a front compartment that can store an external hdd for example. It looks like it can hold 2 lenses + 1 flash but depending on which lenses you own it may not be able to (I own a 18-200 nikkor which is longer and a sb-400 flash, and plan to get a 35mm f/1.8 lens here soon which will fit)
But I have no experience with any other bag, this is my first DSLR and bag purchased.
I got mine on Amazon for $64, but the price went back up to the retail price ($82), not sure why.
