Ortofon has been manufacturing phono cartridges for decades. To this day, they offer replacement needles for even some of their oldest cartridges. Remember that in some cases you have the option to upgrade. For example, the 2M and OM series of cartridges have universal styli, meaning you can upgrade from a Red stylus to a blue or Bronze, or if you have a 10 stylus, you can switch to a 20 or 30.
