I've heard that they are very good. Much thicker steel than any other RSC in the market, and better fire protection. They are expensive, and safes aren't getting any cheaper due to metals and fuel prices. Was that quote with delivery? I priced their 25 cubic foot one with the thinner steel, and it was $1800 without tax, and that was with getting it delivered to a business with a dock and forklift. At home is about 2-300 more. For me, I went with a cheaper safe (Champion) because they're built here and I didn't want to spend that much initially. For me, if I'm going to spend 3-4K on a safe, I'll bump up my budget and get a commercial grade one. Either way, get a safe asap, because break-ins are increasing across America, and the safe's aren't getting any cheaper. I paid an extra $150 for mine from my initial quote in November due to steel and fuel costs.
Once I have a house and more $, I'm getting a Brown.
ETA: There are several members here that have them, and at least one who got a vault door from them. I have never heard anything but good about them.
