I have a steel PST E7-80 for sale. I purchased it new in November 2003 with a hydro stamp of 10/03. It is setup for nitrox with a 200 bar DIN/yoke adapter tank valve. This tank retails for just over $200 without the valve and O2 prep. The size is great, as it weighs less than an AL80. If you're interested, PM me.
