I would wager there would be a higher percentage of gear being moved at the AudioJumble if you need to reduce your collection.
If you want to trade or increase your collection, then the Twang can do that in spades. :sigh: We found that out in three or four years of swap meets - the same people had much the same gear, and you came home with more than you left, which greatly displeased SWMBO.
There still is a certain amount of gotta have action at the jumble, but there are many more buyers than seller/traders, which means most everyone went home with less, and some went home with nothing at all.
It also is good in that no one is going to a person's house, so security concerns are zero. We are in the gym at a Catholic church, too, so if anyone tries anything funny, first they will be smote by a lightening bolt, and then arrested by St. Louis' finest, who as you know don't take sheet from anyone.
And we can use all the funds for the KC roadtrip in a coming lost weekend. I won't have a table, but I do have a car that can make the trip now.
