I'm guessing you're looking for a large one that can accommodate multiple rifles, etc.

Incase its for pistols, I recommend these: http://www.handgunsafe.com
The safe can be mounted to a shelf or another gun safe and can be accessed by touch-finger combination in the dark.

Daddy bought one years ago after my brother shot my sister with a BB gun. (We're from East Texas.) He decided that he drilled gun safety for so many years, but it didn't seem to get through to my brother, so he bought another big safe for the big guns and a small safe for a few handguns. He wanted them out of my brother's reach, yet still quickly accessible. He did his homework, and the gun consumer magazines rated this one as one of the top.

I just ordered one for my handguns, since I'll begin tutoring from the house in a few months. The one on my hip will be safe, but I don't want anyone wandering in my bedroom and playing with my other guns while I'm working with someone else on the other side of the house.
