Another tip for dealing with craigslist: I use a dedicated "disposable" e-mail address (that doesn't include any part of my name) for all correspondence, and I don't give my cell number until I feel it is a done deal. I've done a fair share of transactions and have had a positive experience with all... but you definitely have to be on guard.
Just the other day I had to convince someone NOT to drive 100 miles round-trip to save $10 on something they could buy at their local Walmart or Target. (Anyone need an electric wine bottle opener!?)
