When I'm in buying mode, I check every hour or two. When I'm selling, it has happened that I've had offers within fifteen minutes of posting. Other times, no offers for a month, even though hundreds of hits have been registered on the ad. I think that there are a lot of Audiogoners so the odds are that somebody is watching, especially pros who may be looking to flip a purchase for a quick profit if something appears underpriced. Also keep in mind time zone differences. You check at midnight in the eastern time zone, then go to bed. It's prime time in the west and if they're looking for the same thing as you, it's too late when you get up the next morning.
How frequently do you check Audiogon listings?
Over the past few days I have offered to buy from sellers two items: a CJ amp and Harbeth 7ES speakers. In both cases I inquired probably within 4 - 6 hours after they were listed. In both cases I was the fourth person to offer to buy the amp/speakers (and there were numerous inquiries for both). Both items were listed below blue book value which obviously caused a bit of a feeding frenzy. When I am looking to buy "new" gear, I check listings perhaps five times a day. Apparently, some of you are not being attentive enough to your job assignments at work and are spending far too much time near a computer!! Think of the fall in GNP if this continues!
