First of all, you should be getting cylinders that fit the style of diving you are doing. Using E8-130's for reef dives, or shore dives in rec depths is overkill. Not to mention lugging around all that extra gas and weight. I have two sets of OMS 112's doubles, and a couple of E7-100's from PST, and Faber Hp-80's. I choose which tanks to use for the dive I am doing. That being said, I wont be buying anymore OMS cylinders. My next cylinder purchases will be Pressed Steel. I have dinged my tanks, rubbed off paint, and the bands have taken chunks of paint off of the cylinders, right down to bare metal. Every year that I take them apart for visual, same thing happens. So, I have to repaint them, get rid of the rust, and basically bring them back to life for use in salt water. I like the cylinders, they have a good height, good weight, good buoyancy characteristics, and plenty of gas for the dives that I do. I just hate the paint job.
Do yourself a favor, and get some PST cylinders.
