I kept trying to deal with him because people here recommended him. Again, my conclusion is "he's a hobbyist." Given that he apparently sells to some people and not others, I'm guessing that he sells to his friends, and other people when he has something going on that he needs money for. Any other time, he appears to just hit delete.
Being the capitalist I am, there's nothing wrong with that. He has the right to be a hobbyist, and the right to sell to whomever he wishes, whatever and whenever he wishes. But I certainly wouldn't recommend him with that attitude, and I'd tell people that if you want something from him, settle in for a long haul.
