Although I never had a bad experience with Ebay, Craigslist is the way to go. Stephen has the right idea...meet at a public place and bring a friend.

TIPS:
1.Never communicate with a buyer/seller by email. If they don't give a phone number, then don't deal. Spammers love Craigslist.

2.Never deal with someone who wants the product shipped. This is where Ebay offers some protection. For me, Craigslist means local deals only.

3.Cash only

Anyone have a bad experience with Craigslist or Ebay?

PS: Tim...sorry I'm not in the market for your S910, it's a good local deal. Good Luck.
