I picked up a Cannon brand from Academy for $579... it will hold about 20 long guns comfortably and still have a shelf above them for other things.
Academy runs a 12 month 0% interest special once or twice a year and thats when I got mine.
Safe was heavy but nothing 2 adult men could not handle. A set of piano dollies are the only way to go. Once mine was inside my front door and dollies put on it I moved it to the back of the house by myself.
