HP 8482A Power Sensor and Cable for $100? Did I get ripped off?

I purchased an HP 8482A power sensor with cable on eBay for $117 including tax and shipping. That was more than twice the price of the HP 435B power meter itself! I know the power meter works perfectly and is a beautiful instrument for the price. How about the sensor? Let’s find out. If it works, it’s worth a lot more than what I paid! Thanks for tuning in for your radio fix. Wes W3KW
