How to price it? Well look online for your item in similar conditions to yours and then look at the price people are setting up. Then go from there...
As per selling, avoid eBay, too many horror stories now a days. Craigslist is local, so stick to local buyers, avoid checks, accept cash only and meet in public places (like a mall or coffee shop).
In my experience, Craigslist sells faster. Also, CL you get to keep your total profit.
