My little S3 badge was worn, but I didn't want to get ripped off by the stealers, or even attempt to paint mine, luckily I fount a self adhesive aluminium replacement on eBay for £4.99, perfect fit and just sticks over the original.
No I'm not that much of a mug as to spend near on £30 for tiny bit of plastic.
The 2nd pic is clearly the "reverse" side of the badge fyiOn the listing the first pic looks normal with the 'S3' indented and looks like it could be passed off as a genuine badge but on the second pic the 'S3' looks like it's raised and looks terrible.
Like you I refuse to pay the £30 price tag for a new one which is why I painted mine but it would be interesting to see a better pic of yours.
If your using IOS you could try something like the 'simple resize' app (or similar) to scale the image down, Maybe that could work
