The point I was trying to make about the high costs of a lot of scuba gear was that most of the time, any performance difference that people get from buying high end gear are minor, come at great cost and despite that a lot of people don't seem to mind paying for it. HP tanks on the other hand have a large and obvious advantage over similar dimension LP tanks and generally at a cost of about $100 extra per tank. For example an LP95 vs. an HP119. I can't think of many other scuba products where so little extra money buys you so much extra performance.
