Years ago I won a Namejet auction for a three-word ..com domain I believe in the $125 to $150 range. It had been a developed site PageRank 5. It had some awesome backlink traffic. On a couple of occasions I tried forwarding the traffic to some websites of mine. Eventually I did sell the domain to a developer (around $1250) who seemed to value the pagerank. The keywords were fine for the topic (education) but not ideal for a business. If I saw the domain in a Namejet auction today I would not even bid. The only value was in the backlinks.
