Trying to decide on a safe. Looking at both new and used. Found a new liberty with 12ga steel and 75min fire protection for around $900 delivered. Also found used safes from manufacturers like Fort Knox (45min fire) and amsec (120min fire) for just a little more. Of course I would have to pick those up. Would you guys go for a new one with pretty good stats or an old used one from a higher end brand? Has safe technology advanced much in 20 years?
