Lefty, I didn't know about hydraulics as you described. I've only used typical farm implements (front end loader, dump wagon, ect).I think we are both correct though. Hobbyist-budget hydraulics are not meant for pin-point precision, although with the right equipment (and money) it could be done.
The actuator I listed is high speed and good precision, it's priced at roughly $6-700 bucks. Is anyone able to point me in the right direction of creating the position control for this?
