I've pretty much never been able to sell anything on AGON, but always have had success at USAM. And AGON fees are out of control and not fair in my opinion for the value, or lack thereof, that they provide. I've been very happy with both buy and sell transactions on the "other guys" site, even made some good friends. People are also willing to give better deals as their outlay is lower.
As for equipment availability, I think there's a greater variety available as well, especially for those of us who are on "real world" budgets. Don't get me wrong, I'll spend what need to to get what I want. But there are reasonable limits
And Amen yogiboy and his final comment.
