I call it peace of mind. The tank, foundation, pump, plumbing, wiring, etc. set me back about $1200.00. I did all the work myself except for the hard plumbing into my home which cost me less than $200.00. That was when I learned the average person uses about 175 gallons of water a day, I learned to get by on less than half that in a week, although my seahorses don't understand water rationing.
