How do you guys go about selling stuff on craigslist? like for anything over 100$ I kinda worry that if it were a small expensive item like a lens, that it'd be just so easy for them toget up and walk away or claim it was theirs after you handed it to them for testing out on their camera etc.
I've had good luck selling gear on both Ebay and on Craigslist.
The downside to Craigslist, for me at least, is that I'm definitely not comfortable shipping and face-to-face should only be in a very public place. Most people are honest, but it is always safer to have a witness(es). Craigslist also results in the least "additional" expenses.
The downside to Ebay is the commissions/fees, but... the payment guarantees, etc. make it worth it for me. I've consistently managed to get top reasonable $ for the items I've sold - free market economics at it's best.
