I am looking and pricing the dry stack stone ledge or panel like the one used in DIY network Sweat Equit. Where can I get it?

Where do you live? Try googling or hit the yellow pages for rock and stone supply or even a landscaping supply company. You could also try a lumber yard for faux stone like Corning. Cultured Stone® - Stone Veneer and Brick Veneer (http://www.culturedstone.com/)
