I agree with the Craigslist option. People get freaked out because of horror stories, but I've sold successfully on CL and I find it to be much easier than eBay. These were my own guidelines for CL:
Meet only in public places, Starbucks works perfectly for me.
Cash ONLY sales. No cashier's checks, no counter checks, no wires; cash only.
If you feel hinky about anything, walk away without apology.
