My safe (a Bear brand I bought at the Dallas gunshow about 15 years ago) uses a key lock system. Not as secure as a full-blown combo, but far tougher than most key locks. I'd rank it between the gun lockers and true gun safes in terms of security. Since it's a simple key, night operation is as easy as day, since you can't see the keyhole anyway and it's done all by touch. Takes only seconds to access my guns.
The house I was living in Florida was burglarized. Everything in my safe is still with me. Obviously it works good enough. My roomate, who hid his guns all over his room, had all of his stolen along with various other things he had laying around.
Most of your burglars are kids looking for dope, or dope money. Smash, grab, move. They aren't interested in trying to peel or crack any kind of safe, and even those Wal-mart gun lockers would thwart many. Sure they may tell about your safe, and that's always a concern anyway after a burglary. Still, since my safe HAS survived a burglary unscathed, it works for me.
As for needing to do this in the dark, I could see a situation that you need to. Still, the only loaded gun I keep around the house is the same one I carry. That eliminates any training problems, any chance of facing your own, loaded gun if you interrupt a burglary, and kids getting ahold of it. One gun is probably enough for me. Realistically, I'm not going to have a chance to go rooting around through the gunsafe. If the shooting starts, someone's probably going to loose pretty quick.
