$325 · New Catalina 13cf Pony tank with Sherwood Pro valve and Genesis Yukon Regulator

A top-quality setup, at least that's what I was told, and the equipment reviews appear to back that up. The tank has not seen salt water and the regulator, judging from the condition, has had minimal use. This equipment was purchased not for diving but for an engineering project that required a compressed air source. As it turned out, the regulator, doing what it is supposed to do, reduced the output pressure far below what we needed (and we needed 600-800 psi). So it remains in virtually brand new condition ready for someone's diving adventure.
