I have to concur. In the few years I have been posting to this site, I have made many friends. Some have been more gracious than I could have ever wished for.
Almost all of my purchases here have been fabulous. I prefer to do business in person, and have done that via this site. Three times.
In all of the instances, it was never just a here's your money, thanks for the component. Rather, I have spent a significant amount of time with the person. Talking about the component, talking about their system, talking about my system, talking about audio, talking about other things.
All three people I have met were extremely nice people. The kind of people you WANT to do business with. In the most recent deal, I talked to the person several times before the weekend came to pick up the item, spent several hours at his home, and have spoken to him several times since. He has called three times just to ask how I liked the component, offer advice in maximizing its performance, tips for the future, and offered to put me in contact with others as well.
Kudos to Audiogon, and its members!
