Bump! I just picked one of the lower end units up @ the Walmart Black Friday sale. The only difference is the key over ride the unit for sale here has. Which is a nice feature, in case you really don't trust the other person with the combo, lol. These Sentry safe's are built like a tank, weigh it just over 100 lbs They have a pry resistant hinge, it's hard to explain but if locked and the hinge was cut completely off, the door would still not open! Also the Four 1" bolts, air/water tight seal and fire proof unit. These are real well made safes, and once bolted to floor you stuff will be secure for sure!
