Fireplace Mantles: Today's Obsession

I really, really REALLY want one of those old-fashioned marble fireplace facades in my bedroom. I just find them so beautiful and charming. I found a place called Old House Parts in Maine that sells them for around $450-650. I imagine shipping adds a couple more hundred, but this might be one of those things I eventually splurge on.

The top one is $450 and I just love the curvy carving. The bottom one is really nice, too. I don't have a lot of depth to spare in the apartment, so I just need the facade to stick out and give the illusion of a beautiful old brownstone parlor. The radiator under the window can provide the heat (though I do want a nice basic cover for that, too.)
