Be careful with any repainted badges. I picked up a brushed titanium refinished OEM badge, and had to send it back twice due to very poor painting and quality. The picture in the Ebay ad you linked shows lots of extra black paint, and that's likely the best one of the bunch that they took a picture of.
You may also want to clear-coat it....even after getting a good crest this is a before/after of what happened to mine after only ~3k miles.

(actually its an 'after/before' shot!)
