At the present time, it worth reg fee. (the hyphen kills the potential) In the near future, if you develop it, you might get something good for it. If you develop a 3D map site: you'll have a good site in your hands, with a great keyword name.
That's crazy... In my opinion, it's worth reg fee - low $xx. If you could get $400+ for it, that would be amazing TBH
maybe but its documented i wouldnt have thought so either but.................. 2010 new 3d era upon us who knows
