I bought a phone from a guy on Craigslist, a year ago. I'm using it, at this very moment, to make this forum post. My van, which my wife and I refer to as "Old Faithful", also came from Craigslist. I've made a few Ebay purchases, as well. I haven't faired to badly there, either. Of course, with one exception, I bought new stuff from Ebay. With Craigslist, it's best to meet the other party in a public place, and inspect the merchandise. A reputable person should have no objection to that.
