There's an evil craigslist scam that involves selling of expensive items for a steep discount. Basically it's not stolen goods but a robbery. For craigslist sales, one typically pays by cash so it is easy for the scammers to lure the victim to a seedy place (controlled by them) and relieve them of the cash. A friend almost got nabbed this way but he was a bit absentminded and went with a checkbook instead (for a high-end computer worth thousands). Lucky him. An indicator is that the meeting place is public but out-of-the-way and may involve a dead-end street.

Not that I'm saying your craigslist find is such a scam...
