The best site is postlets.com. You will have to register, but you will be able to create a very professional listing and it will post to over 40 different websites, including those listed in the previous post. You can also post the listing to Craigslist, but you will have to copy and past the html code from Postlets (they instruct you on how to do this) and paste it into a post on Craigslist. If you have questions or need help, contact me at my website. Regards.
