Definetly get one that is fire rated!!!
I have a Cannon, all the new ones seem to have digital locks mine is an tumbler dial. The only proub I seem to have is the numbers on the dial seem to get smaller every year? Must be a an issue with the alloys used, darned if I wont need to put my glasses on soon to open that safe. I contacted Cannon service dept direct and informed them of the shrinking number proublem. They assured me that the QA/QC at their mfg facility was "top of the line" and that there must be another reason for the numbers on the dial to be shrinking, possibly local environmental issues?
