I found this interesting from:
http://domainnamewire.com/
Cowboys.com was the highest sale in the silent auction, which just concluded. Unofficial results show the next highest sale is Xmas.com, which sold for $294,000. Here are other notable sales from the auction:
FishingPole.com $58,900 - this will make a good fishing enthusiast site. I think FishingPoles.com is better, but this is still a good name.
Carburetors.com $40,000 - Tough to spell; worth buying the typo versions as well
HawaiianCruises.com $38,888 - Good category killer for Hawaii tourism
TrainSets.com $36,300 - Strong e-commerce potential
Math.net $35,300 - Strong price for a good .net; revenue potential and use unclear but many possibilities
PaymentCalculator.com - $35,300 - Great lead gen domain; provide a loan calculator and capture info for mortgage refinancing
Locket.com $33,000 ...
There are many more domain names and prices listed.
