I have one, though I admittedly didn't pay retail for it, got in on the pre-order. Had it at the last KSTG....
It's pricey partially because a LOT of thought went into how it's configured. Everything I carried in one of those 5.11 range bags, fits in the A-Range, but is WAY easier to carry because it doesn't sag under weight. I'm still futzing with a few things with Blue Force Gear Dapper accessories for the velcro portions, because the Tactigami attachments are only just trickling forward (even if I wanted any)....but it's been fantastic for the whopping 3weeks I've had it.
All zippers are TSA-lockable, there's plastic-coated steel cable that both supports the bottom half and provides for the entire bag to be cable-locked if you want.
It's not as easy to carry more than one spare handgun, unless you ditch carrying ammo in the trays in favor of some other way...but I also carry a lot of crap like medicine-cabinet/hygiene items, booboo kit, handgun spare parts, tools...the list goes on. I use it as a general "go-to-range" bag, the thing that ALWAYS goes the range with me, but is equipped to be complete toward supporting pistol use. Rifle-specific stuff is in it's own bag setup.
If you still want something like the 5.11 bag, just get the Midway version, save yourself the $$$. You'll get the same usage out of the Midway bags, and spend 50% of what you would for 5.11.
