For all what was said above. They last. So go on line and buy a used one for your second vehicle.
They go cheap because no one is willing to pay any where's near the new price. Mine was only a couple years old and I ended up selling it for 400 bucks. I see them for 250 all the time.
Just try and buy a later model similar to what is being sold new now.
