I've got a MotherLoad in black...
I think I paid about $125 for it at the BX, MSRP off Camelbak's web site is $169. The sucker is huge and carries a lot of crap, and it is a very comfortable backpack when it has to be worn for extended periods of time. It can haul "over 2100 cu. in. (35 liters) of gear and 100 ounces (3 liters) of water" according to their web site. However, I have been looking at a BFM, due to its addition 7 liters of carrying capacity (2600 cu in) and additional outside pockets. I have to carry a lot of "stuff" (I usually carry an extra bag as well) and the BFM might hold it all. The BX also sells them for around $150, whereas CamelBak lists them for $199. In case anyone hasn't clued in yet, buy them at the BX! AAFES on-line does not carry them, you get redirected to Brigade Quartermasters, who have the ML but not the BFM. They also list a "military price" which is cheaper than retail, but you must access their web site through CentricMall to get it.
I really like the design and capabilities of the ML and BFM. They are well-built packs and will probably outlast me. The one thing I don't like is the ML tends not to stand up on its own when set down, it carries a lot of weight midway up the pack or higher, so the COG causes it to fall over. That only sucks as it gets set down in some dirty places, and then the whole pack is covered in crap. But the only way I can figure out to fix that would be some sort of internal frame, which would only add weight and reduce carrying capacity; so I just live with it, it is really a minor issue.
But I gotta admit, bags fall into the Cool Gadgets category of things I am always on the hunt for!
