Thank you for replying. Your post is a good example that illustrates my point, so I'm going to entertain a response for one last time. There is no suggestion in that thread that the seller is a "con artist", only complaints that the price is unjustified. Selling an item at exuberant price does not make one a con artist. If there is a buyer willing to pay the set price, then both parties walk away happy. For the buyer to be conned, the seller would have to run away with the money or send something that did not match the description. The seller provided an option for purchasing the device via a secure method (eBay) that includes a money back guarantee. He has 100% positive feedback on an account that over 13 years old. He also offered an option for an offline deal which could be susceptible to a con. If someone chooses the offline option over the secure method and then ends up being conned, they've no one to blame but themselves.
Going back to my point... these days on TMO, you make a contribution to a thread which might be something as trivial as sharing a link about a relevant news update, and it gets torn apart. So you feel the need to justify your contribution, only for that to get torn apart. So you justify your justification, and it goes on and on and it gets to the point where you question why you bothered contributing anything in the first place.
