I'm sure everybody has their experiences as a consumer potentially with anyone at times.
Dan is not a saint, and I don't think anyone was suggesting that. But his service is generally pretty good, and he doesn't mind helping and sharing his knowledge with people, and he does know his shit as well as have good prices. I have asked him questions elsewhere that he hasn't bothered answering, which I thought was either rude, or he is too busy -however like anyone in business he has to focus on what will earn him money.
I think there are probably a LOT more positive experiences for every negative experience that anyone has had with Dan.
