How much is your site worth?

While reading a friends blog today I found a cool tool which gives an estimate of how much your site or anyones site for that matter is worth. Just enter that domain at leapfish.com and it will calculate a price based on the length of the domain, if the domain is .com or .net etc., and the amount of search engines results. Just for fun I took a domain I have had for quite a long time www.hostingcharm.com which is where I have sold web hosting for the past 3 years and entered it into leapfish. It tells me hostingcharm.com is worth 525 bucks. I guess thats ok for the domain but I would never sell cheap prescription drugs without prescription it for that since it comes along with all my hosting clients of course
