Domain Name Valuation has always been a tricky task, and it's often amazing to see the vast differences in valuations suggested from one source to another. This said, 3-Character domains are somewhat unique in that they can be valued somewhat more accurately due to three very important features, which include:
* their length * their character composition * their comparable recent sales data

Will .info domains do ? I have one but if it would have been .com or .net it would have sold for much more then the .info one. These days there is a great demand for LLLL domains and they will get sold for much more afterwards. :)
