I just got a Fishpond Dakota and my wife has a Simms GTS Rod and Reel Vault (which I think is what replaced the Bounty Hunter Rod Vault mentioned above). The difference, as far as I can tell, is that the Simms is about 1.5" longer and can supposedly accommodate a 9'6" rod, though we haven't tried because we don't have any. You'll only notice the difference if you sit them next to each other. The Simms has backpack straps and the Fishpond has a shoulder strap. My regular carryon is a shoulder strap and hers is a backpack so we should probably trade... Anyway, both are good solutions, and the differences are minimal.
I saw a Field & Stream branded version at Dick's that looks exactly like the Allen linked above. Thought about picking it up and saving $100, but the mesh on the front pockets seemed likely to tear. Given Maliberti's experience, maybe I should have. I haven't seen them all in person, but the Orvis, Fishpond, Simms, Allen, and Field & Stream bags all seem like basically the same thing and like good solutions for carrying multiple rods and reels as well as your lines, leaders, etc.
