Out of the two I would definately do the Vorsteiner, but personally I would look at the eBay replicas. There are good products out there in the $300 or less range. Just find a reputable eBay seller.
What color is your car? I really like the look of an unpainted carbon fiber spoiler. I think it provides a nice aggressive contrast.
