I did the $99 test at 23andMe. It is not a very deep ancestry test but I came out R-L21 which is all I really need to know since I have excellent documentation for my paternal line.

A distant relation on my McElmurry line tested positive for R-M222, the infamous "Niall of the Nine Hostages" line. I have been following the action on the R-M222 boards but it will probably be six to twelve months before they sort out all the new markers discovered by Full Genome, Big Y, and Chromo2.
