From the title of your post I thought you wanted appraisals on domains.info and domains.net. I felt tricked :o
Due to the low volume of NCSI and the fact that most of the search results relate to the DOD, and the fact that its .info I'd put the re-sale value at mid $xx to very low $xxx.
Ubers.. I am not showing 7 million google results, I am also showing a coupld hundren thousand. I would try to find a computer geek that wants it and anything more than reg fee would be good.
Good luck.
