I found this fun little tool that goes out and tells you what your webpage is worth is you were to sell it to someone else. I don’t think it’s accurate at all, but it was fun to play around with. The site does basic analysis of known traffic (Alexa) and sources into your site via Google, Yahoo, and AltaVista. It also WhoIs’ your site to find out how long it’s been around.
