My experience selling has been mixed, but generally the audiogon crowd is the best there is. I do have one concern, and that is abuse of the AGS. I've seen alot of clowns sell 7/10 pieces as 8/10 and 9/10, and I've been burned before when buying. The last time I sold a 7/10 (which would be an 8/10 for most posters, who are more liberal), I got to experience first-hand the undercurrent of low-ballers that run thick in this site, getting ridiculous offers and hard times from people while offering a sternly-graded item at very low price. Of note, the low-ball offers started absolutely raining in after the auction was a few days old. That sort of experience makes me value EVEN MORE the nice people I've met here. You just need to be selective and keep to your selling principles.
What venues are best for selling used equipment?
I haven't sold much audio equipment, though I have sold a couple of items through Audiomart, and I have sold non-audio equipment through Ebay. I have recently joined Audiogon, and purchased a receiver by means of an Audiogon ad. Do any of you have enough experience with these or other venues, to compare the relative merits of each?
