I always take a look at trader rating, past trades, even post history sometimes if I feel I need to get a feel for the person. And since I have a low(er) trader rating than most, I expect some scrutiny as well. But the site says, use paypal, don't send money as a gift, etc, and that is just to protect people. For the most part the fees aren't too crazy unless your selling high $$ stuff all the time, and at least you get to cut out the middle men like ebay.
