I have a brand-new YCCC SO2R Box (Plus), still in kit form, never assembled, still in the box as received from YCCC. I bought this about four years directly from YCCC with the intention of building it and setting up SO2R. Alas, another one of my uncompleted projects! Buy mine for $100. Pick up in Tamarac or Stuart, or I can ship. Mike, W4UM
