Cut the guy a break, he got a 2k off ebay and found it it had an accel in it and he doesn't have any clue how to use it and doesn't want it. I've bought a1ks of ebay and found accels in them and had a hell of a time figuring out how to get them to work. I don't see anything particularly malicious about this listing. AS-IS, treat it as possibly broken, don't spend money on it you don't mind loosing.
