Such naivity amongst even the most die-hard 'Gon'ers. As with anything, you do need to be careful when buying AND selling on this site. Everyone keeps mentioning that there are only "18" disputes. That's not exactly true. There are 18 PUBLIC disputes, but there are countless others where AudiogoN had adequate information to make a recommendation w/o posting the dispute in the forums.
I've been burned a number of times. Conversely, I've also met some tremendous people who share the same passion for music.
I've had the best luck with posting ads for a "local sale". This way, you get the best of both worlds. The great reach and resources of the AudiogoN and the extra peace of mind that you're dealing with somebody locally. It goes a long way in reducing the risk of mis-matched expectations, shipping damage...or worse.
Finally, I would agree that shipping large, heavy or ackward items such as speakers and tts is RISKY business. Local sale is the ONLY way to go with such items.
