As for reflections of seller, I have some story - I bought Lynx 5000 from old man, who has put his real portrait in eBay profile (I can't remember any other seller doing so). Most of photographic gear listings from him contain very detailed description how gear looks cosmetically, what works and what not, if he had tested gear with film and some pictures with backyard or sellers reflection in mirror, with note "I will send sample pictures to winner".
OK, maybe buyer doesn't want or need pictures of old man, but that's the way he keeps on; it's better if he sells on eBay earning very good feedback than buzzing over table to his wife or fighting with neighbor "why in hell are you feeding damn birds".
Do I have pics of old man? No, Lynx were clearly listed as "shutter inop." so he didn't have pics taken with this camera.
