I agree with Kelly, it depends on what you are looking for. Don't overlook MSN (LIVE) and Yahoo paid searches as well...although you do get less traffic than Google, it can be cheaper and in many cases more targeted traffic. Selling on eBay and getting customers to look at your "about me" page then allows you to link from eBay to your web site...and it's free. Don't forget craigslist too.....especially locally.... it cost's nothing.
