I bought a Sports Afield from Costco some years back for cheap. About 800lbs, but I wouldn't buy again. I got what I paid for. Door doesn't seem to seal well and would not give it a chance in a fire or against any "professional ". My parents have a Canon safe and is very high quality and would consider a similar one next purchase.
My only suggestion... plan to get as big as possible because you run out of room before you're done loading the first time.
