I have bought and sold several sites over the years. I was also a fairly active domainer (guy who sells/buys domain names) for a year or two and keep a list of 500+ in my portfolio.
The value of a site greatly depends on the ability to generate revenue and promotion, which is far easier to quantify today than it was a few years ago. If you are ever up in Seattle drop me a line and we can have coffee sometime and chat.
