So there's this thing on the classifieds:http://www.thumpertalk.com/classifieds/showproduct.php?product=70230&cat=8 It's EXACTLY what I want and I've been looking for a good deal on something like this for MONTHS. Anyway, how do I know this isn't a scammer? Do we go through paypal? Do I just send the money to his yahoo? How do I know, and how do we buy things on here?
