Wondering if anyone knows of a 'well priced' ~14 gun cabinet out there? Someone provided a link for one either on here or another forum which was around £250 but I can't for the life of me find it.

I'm rapidly running out of space and don't have any other locations I could put a second safe, which would be the obvious answer. I'd contemplated bolting a second one on to the side of the existing one, but that one is already connected by its side, rather than its wider back and two bolted together would give significant leverage to pull them both off the wall (the wall to the rear of the safe is just plasterboard).
The cabinet needs to be out of sight, not just to keep the police happy but also the missus! The current one is inside a sliding wardrobe and the obvious answer would be to mirror the same arrangement in the bedroom to the side of the main bedroom but in order to put the safe in i'd lose two rails for clothes and I've been categorically told that ain't happening! The loft isn't boarded out and the joist arrangement means I could barely get a break-down shotgun cabinet against the wall, likewise the cupboard under the stairs isn't tall enough to get a rifle length cabinet under there, gggrrr. I've got a garage with plenty of wall space but I know the police aren't keen on that, plus the temperature varies wildy as its single skin on one side.
So, the cheapest option is to install a wider cabinet in the position of the current one, but the only wider cabinet I've spotted so far is the Brattonsound Titan which is £640-660, which isn't going to work for me!
Ideas?
