Take a good look at CHAMPION Safes. This summer I bought one as a second safe and love it.

My needs were different - They ultimately customized one to hold longguns only, and I've got my current best 18 in there with room for reasonably 8 or so more.

Their "Medallion" series are the ones for you to look at.

Good luck, and as another member wisely pointed out, you will get more guns so keep that thought in mind while you search.
