Replacing Glass Fireplace Doors

[2LaneCruzer]

I'm looking to replace my old glass fireplace doors with some that are sized to fit inside the fireplace instead of just on the outside. They look a lot better, plus if you ever have a chimney fire, you have a great deal of control (chimney fires are a white knuckle experience, let me tell you). The problem: The local fireplace folks want about $1200 for the basic unit, which I think is absurd. Has anyone found a practical solution or know of any dependable, mail order companies that will make them for a reasonable price? Lowes have some pretty nice units in the $400 range, but here again, they fit on the outside of the fireplace. I'll go back with this type unit before I pay $1200 up.

Thanks in advance,
Dennis
