The only thing that bugs me about the PCL units is that they are set up so they are fully adjustable and can be calibrated/serviced but you'll be hard pushed to find someone to calibrate one for less than the cost of just buying a new one.
They have a little screw hole where they are supposed to be oiled but I suspect like me nobody ever does that
