I am searching for a "Tool in position sensor" for a Biesse Rover 346. Our #2 router motor has gone out and I am going to have it rebuilt and I need both sensors for the router in order for it to work. I have contacted Biesse and they are asking $430.00 each for these sensors. Does anyone know of a cross reference or of a supplier where I can find these sensors? Just hard for me to believe that these sensors would be that much for something smaller than a spark plugs.
