Thanks for all the comments. It is extremely helpful and much appreciated ~ rep added all around. I of course knew that the syntax (word order) of these names was not ideal but I was not aware that bad syntax is such a fatal flaw. I spent some time this afternoon on DNSalePrice.com and I see what you mean. With one or two minor exceptions the names all make sense syntactically.
Live and learn.
Josh, thanks for the additional clarification of Estibot. I should add that I wasn't relying exclusively on the Estibot appraisals. I also use OVT, keyword discovery, SmartPageRank, google, yahoo, and other data. But the high values on Estibot did compel me to pull the trigger on these particular names.
I reviewed the Estibot findings and I see what you mean about how the dot net availability influences the Estibot valuation. But it also values other sites I bought (I may have gone a little overboard) highly that are not gone in dot net. For example, CarDallasUsed.com (400 USD), CarDenverUsed.com (320 USD), and CarPhiladelphia.com (280 USD) are all available in dot net. I attributed the values here to the Keyword Frequency, PPC Ads Score, and Exact Searches/mo figures, which are all okay for these domains. What do you think?
