I own the domain www.freepccheckup.com
This is a unique domain that has been appraised at $5,000. However, I feel it is a lot more valuable. All the big box retailers like circuit city (firedog) and Best Buy (geek squad) are using the free PC Check up as a slogan to get more customers into the stores.
So, if someone has a contact there, I would say there is a potential match.
This domain is also valuable for online scanning of viruses, RAM, Drivers, etc.
