Well, this section is specifically for domain names. ClickATon.com - I actually like quite a bit, and have a very similar domain - ClickItOut <dot> com - which will be my Domain Consultation service.
I think its catchy, brandable - and thats what most advertisers want, traffic. Clicks = Traffic. Also sounds like a possible domain name for a parking site. Anyhow, value is definetly in the eye of th ebeholder and development on this one.
If your site is making money, that will contribute to its value, but stand alone, I think you would be fortunate to see it sell for $10-15.
