UPDATED: 4-22-2016: My personal experience with Sentry’s model A5882 was excellent, but it has been discontinued. It seems that Sears no longer carries it, or anything directly comparable. (Oh, Sears. 8,( How I miss the retailer you were. )
As near as I can tell, this is the closest replacement for Sentry’s A5882. Reviews below are mixed, so do your own due diligence.
Purchasing options and specifications can be found on Sentry’s own site here: http://www.sentrysafe.com/Products/191/OA5848_Digital_Fire_Safe_
