I was wondering if anyone has experience of selling an existing website to another company, such as to one of the aggregating networks (iBoost, Internet.com, etc.) or to another 3rd party.

The site in question, Emailaddresses.com, gets between 150,000 - 175,000 unique visitors a month and approximately 700,000 pageviews a month, with between $4,000 - $10,000 a month in advertising/sponsorship/affiliate program revenues.

It is the leading site in its niche (reviews of free email services and service providers)

What's it worth? Who would buy it? How would I sell?

I'll say immediately that I'm not looking to sell *right now* but I want to keep an eye on the market for a site such as mine...

Many thanks for your time and help.
