Too many bad experiences on Craigslist. People try to play it off and say they brought less money one one (they also ask if you have change; mention in post you do not carry change), another person who gave me fake money and ran away after...
I highly recommend if you do, take your brother or dad (or someone who knows technology) and meet at Starbucks or crowded place. On the other hand, bring a counterfeit pen (Staples, Office Depot), you chose the place (pickup only), and tell them the price you are asking for is firm (no trades, no bargaining). Following those steps will clear out low ballers, scammers.
eBay is pretty much the only place you can sell besides Craigslist....safewise. Much easier and safer for payments with Paypal.
