Everything on ebay is knock-off junk. The chrome will probably peel in no time flat.
Just so you know, I've been scouring ebay/craigslist/forums for the last almost 12 months trying to find a good deal on a used 05/07 chrome front bumper. Every time one popped up, it was gone in no time, and most of the time it wasn't even a great deal.
I ended up getting a new one from Sunrise Ford (sponsor here) for under $300 NEW. They even cut me a deal on shipping. I got a couple other things but the total price was around $325 shipped on a new one, no brackets, just the bumper itself. Not a bad deal. Look at the junk on ebay, it's almost that price...
