Meh - I've found most sellers are clueless as to pricing on Craig's list. At least on eBay there's an international presence and other listings to keep things in check.
Worst of all is computer equipment. People don't truly appreciate how bad these retain their value, and always base it on what they spent to buy it, vs fair market value, or the price of a new, better model.
For instance, this guy: Why buy 1 yr old when you can get this year's better model for less, brand new?
