Craigslist is the best. I’ve found apartments, sold computers, and bought all sorts of items with it since about 2000. Craigslist gets great search results as well. For example, a while back I had discovered an interesting niche for printing skate board decks. I posted an ad on Craigslist offering the service in the Bay Area and linked the ad to a page on my own website that went into more detail. The Craigslist ad hit the first page of Google in a matter of hours for the term Skate Board Printing - and the page on my website got a significant boost as well. In fact, that page is still in the top 10. Here is a great article I found on how you can get the most out of Craigslist for your site.
