Get your own classified board on your website – try out Edgeio’s Marketplaces in beta.  Keith explains,

The idea of allowing any web site to create a free classifieds board, and to take listings into it – either in return for a fee or for free – is core to the first marketplaces product – Classifieds Boards. Theoretically this should make it possible for web sites to do what newspapers and magazines have done for hundreds of years – make revenue from classified listings alongside their revenue for advertising.
