I am a Master Scuba Diver newly certified by the NACD as a cavern diver wanting to continue my education but I am needing to upgrade my gear. I have a very nice O/W rig but want to keep one for O/W and one for caves. I am looking for used but good gear. I need

SS Backplate
Wings
Basic Harness
Steel Doubles current Hydro and O2 Clean
Reg w/ 84" hose w/ Octo
Mult Gas Computer

I am not wanting off name brands but somethings proven and reliable. I plan on getting everything overhauled before getting wet. Any suggestions welcome.
