Preferably, you get the largest pressure tank or array of pressure tanks that you can afford. This will greatly extend the life of your pump as it will not need to kick on and off constantly. It also reduces strain on your fixtures and piping system when the pump first kicks on.
FYI, a rubber bladder/rubber diaphragm pressure tank makes water taste fucking nasty for over a month. A bladderless tank usually doesn't do that, but it will depend on the tank lining.
