NONE that stores sell!
Watched a gun safe broke in to in a TV film.
Had placed duck tape over the name on the door.
Two men walked up to the safe and pushed it on it's back.
One had a pinch bar, type used by the rail roads in the day and the other a a wrecking bar the kind that looks like a walking cane and opened up the safe in under three minutes with out any rush. By hitting the safe on the non hinged side of the door. Could have done the same if left standing, just easier to work on on it's back.
So I went to plan B (not use any) safe of that type.
