I handle everything I trade just like I do purchases. I'm selling something, and I have a lot of good feedback and the people of the forum know me, so when dealing with a new member, I tell them that since I'm the one with feedback and they're a brand new member, all purchases will have to be paid for before the item is shipped. Meaning, I will have the item boxed up and ready to go. When I receive their item and check everything out, I will ship their item immidiately. If they aren't comfortable with that, I hold on to my stuff. We just had a member get scammed out of $500 bucks from a guy listing a baja in the for sale section.
