...
And here is the Fort Knox safe I was talking about. It's great:
Very nice.
And it's 10 gauge, so if you secure it properly will take a small crow bar or heavy screwdriver etc. to get into (which is pretty good for a box just over a buck.) The simplex lock alone is worth most of that money. I can't recommend any low security device more. ... then again there is this little aircraft aluminum auto safe that I don't tell people about....

Gauge
The sheet metal gauge (sometimes spelled gage) indicates the standard thickness of sheet metal for a specific material. For most materials, as the gauge number increases, the material thickness decreases.
Sheet metal thickness gauges for steel are based on the weight of steel, allowing more efficient calculation of the cost of material used. The weight of steel per square foot per inch of thickness is 41.82 lb (18.96 kg), this is known as the Manufacturers' Standard Gage for Sheet Steel.[4] For other materials, such as aluminium and brass, the thicknesses will be different.
