best fm transmitter for ps2/xbox?

[GranAmed]

Im looking to put a ps2 in my ride, but my headunit doesnt have any aux rca inputs. so i guess im stuck with a transmitter. what do you guys reccomend. and i could route it to sit next to my antenna if need be.

a little research shows that a transmitter that connects to the cars antenna cable is my best bet. anyone know of a good one that isnt going to cost an arm n a leg?
