There's aftermarket. IIRC, the ones from the Tire Rack cost something like $40 each... if you buy the wheels and tires from them, they'll install the sensors for free (they don't carry Mopar rims though).
The only issue I had is that the TR installed one of my sensors incorrectly and the thing broke in a few short miles. I had the dealer replace it and Tire Rack refunded me the cost of the sensor (which was less than the $100 the dealer charged me to do it, but I was on the way to the dealer when it happened so I just dealt with it there).
