My Black 335i will get a full coverage front "clear bra" in Atlanta on the day after my PCD (next week).
http://chuforiagraffix.com/ that's the guy I'm using. I know him from the Lotus crowd, he does fantastic work.
He uses XPEL brand film.
My cost is going to be 1k-1.5k. This is much cheaper than a repaint...especially when you consider that most repaints suck, and are obvious repaints, and will decrease the value of your car (repaint often means wrecked...no dealer is going to take you on your word that you had a BMW repainted due to rock chips.
My Elise still has the OEM clear bra, and the car is rock chip free...
