Yea, I was just cruising the web, stumbled on it about three years ago, and I've been a gonner ever since. (Actaully bought my first Thiels from the Audioreview classifieds back when they were worth while -- but it's been nothing but the Gon ever since).
As for dealers and the internet, I was stunned to be talking with one of the major high-end shops here in NYC about trade-ins and have them tell me that I'd be better off selling on "Audiogon or some other place on the web." Shoot, I knew that, but I was seriously considering the convenience factor of a trade-in and there he goes sending me back to the 'Gon. It's hardly news, but I thought it was a shockingly progressive and enlightened stance to be getting from a major dealer. Another large dealer, the one with possibly the largest selection/stock of on-site used gear in the business, ditched it entirley. All gone--officially no longer focusing on the used business. For all the chatter about how the internet is reshaping the industry, here's at least two significant players who've thrown in the towel as far as competing in the used market goes.
