Chadwick, Yesterday @ the lost and found Horning's Icebowl, I saw a Black Aluminum marker that had engraved #8 Corbett. Do you know who made these, or how to get my hands on one? It was not a run of the mill innova marker.
the only metal minis that I am aware of are the ones Dynamic Discs makes. http://www.dynamicdiscs.net/Dynamic-Discs-Metal-Mini-Disc-Golf-Engraved-Marker-p/4548.htm
