Pete, there many great brands to choose from. I prefer Liberty because their bolt works are stronger than most. Assuming nothing has changed of course.
I would be hesitant to buy from any big box store. Most of the time the safes are made in China even though they have a familiar name and look like US made.
Where I used to work, we had a contract with a buyer than bought all of the damaged safes/lost combinations from Costco, Tractor Supply, and Sams Club. On the outside you couldn't tell they were Chinese made. But once we opened them up for repairs, the work was terrible. No two were the same.
Find a safe store or local locksmith that sells or can order your safe. And as much as I hate big box stores Cabelas and Bass Pro sometimes have very good sales on American made safes.
Liberty, American Security, Fort Knox, Cannon, Browning and several others would serve you well. And as usual stay away from electronic locks if you can. Have it delivered and bolted down. Get a dehumidifier and gun socks. Keep it a place where the temperature is constant. Buy bigger.
Find the best deal on something American made and you'll be fine.
