Wally World has a pretty nice Sentry combo lock 14 gun model for $329...just picked one up myself last week. It weighs 315lbs, so it's much heavier duty than the Homaks I've seen. Realistically, you can expect to get about AR/FAL type guns in one of these...more if you don't have lots of stuff with pistol grips. I got 9 long guns, including a couple of ARs, and my varmint class bench gun that takes up a lot of room.
I have another Sentry that's a little smaller than this one, and paid $299 for that one 2 years ago. The one I got last week is bigger and nicer, so I'd say it's an excellent value. Once again, I managed to get 9 long guns in that one, but it's kinda cramped lol. One or 2 more safes, and I'll have all my stuff locked up hehehe.
I think Bass Pro sells Sentry safes as well, iirc.
