E-Bay/Ham Fest

Greetings!
I know a number of people that have bought off of E-Bay and have never had a problem, yet. I can see where there could be a problem is someone wanted to rip you off. I really would feel safer buying an item at a Ham Fest. At a Ham Fest you would be able to look at the unit right in front of you knowing that it really exist, and not just some discription and a picture on a web site where you send your money and hope you get that item you wanted in return.
