I was just wondering what the going rate is for the SI Mechanism key chain (Black Version) is? I have seen them on eBay, but they are going for like $70 bucks. While the kelp green one is only $16 bucks.
They are worth about 15 dollars, but on eBay you can sell for what ever you want! That's why you see a various price range, people trying to rip people off.
