When buying a safe realize that there is no agreed upon standard with regards to fire resistance. So, it's all "apples and oranges" when you compare safes.
Most (the vast majority) of safes, and all of them at the price point you want, use plain old sheetrock (drywall) as the fire retardant. Given that, you're better off paying attention to the gauge of steel used in the walls than anything else.
Also, to make it useful you will have to bolt the safe to the floor. If you don't, it will be easy for anyone to tip it over and break it open.
