they aren't charging for the service, on their site they said they are so backed up with requests that they have had to direct people and or still directing incoming people who wish to have the test done to another organization that charges a fee but they themselves aren't charging but not taking on any new cases.
truessence brung up a series on PBS that had a whole episode on this very subject. i saw the episode and it was really good. The interesting thing was henry louis gates jr.( the conducter of the series who is also big into african culture, has done several documentaries on africa and heads the african studies program at harvard) came out with very little african origin to his DNA he was mostly european.
i would love to get this done but i don't know if i would trust the results really, they may make something up and i would never know- i know nothing about DNA testing and genetic code and whatnot.
