Hi Doug,
Here is a good informational article about what to consider when buying a safe :

I have settled on the 20"x20"x60" sized safes. They are easy to move yet can still be bolted to a concrete floor and can even be bolted/ganged together, side-by-side. I usually pick mine up at the Reno gun show (out of box specials) for around $ 300...brand is Liberty (correction on 6-4-5 : Brand is American Security).
Regards,
Pete...
