There is still demand for domain names. The high prices are certainly not there anymore. Also, the demand for marginal names has vanished (like names with i and e, hyphens, etc).
Having sold about 100 names in the aftermarket, I still see interest in one-word names and VERY STRONG 2 word names that are natural phrases. Prices are very low though. If you are a speculator, now it the time to accumulate.
My best sellers are generally short one word .orgs and medium length .com names. My general sales range is $300 - $500 on short one-word .org names, and $100 - $1000 on .com names, depending on the quality of the name and traffic. With one word .nets I typically get $500 - $750.
My opinion only.
