Do you see where this is going? Accuracy, while related, is different than repeatability particularly when attempting to achieve a pre-determined point in space. In addition, the way each actuator is deployed has significant influence in the result.
While there are numerous actuator styles/types available that are manufactured to various degrees of precision and subsequent cost, this type of actuator may be highly repeatable without it being highly accurate. The key to success is understanding the system requirements of your application, and choosing the actuator accordingly. By doing so, excess cost is avoided, rendering the best overall value.
