Need some ideas on the value of these .US domains?
Dirk - I don't think any of the valuation models can deal with .us right now, it's too new. Check in hand determines value. Hold onto your names, they will appreciate in time.
.com/.org/.net have been around for 10 years now, lots of history and examples to work with.
My take on some of the name values is that ICANN has limited new TLD offerings, thereby creating high demand and high prices.
I still believe that Internet growth will be exponential, and the demand for good names will always be there.
I have great hopes for the .us TLD, but less enthusiasm for .biz, .info, or most of the proposed .pro, .aero, .name, .coop (chicken coop??) names.
