Sonny;
Your price range absolutely precludes getting a safe, a real one, not a Liberty RSC. I'd get a cabinet that met my needs & then concentrate on stealth.
Hide it, disguise it, spend money there rather than spend another $100.00 that gets you nothing more than ineffective decals, or other useless 'bumph'.
You can't get effective fire protection at your price level, don't worry about it, & save for a good safe down the line. If you want to research a little, do a search on this site for RSC.
