I bought the Ancestry.com test. I couldn’t decide between that one and 23 and me. The deciding factor was concerns about the their sale of data to drug and medical research companies. So I went with Ancestry, who just tests for genealogical data, not health and medical.
Anyone else?
One thing I noticed is that Ancestry does recheck DNA results when more matches come in. Last year when I did it, I got something like 23% Irish, 33% Western European, 20% Great Britain/Scotland, 10% Iberian Peninsula, and the rest from southern Europe, Ashkenazi, and North African.
Last month, they updated it, making it something like 86% NW European/English/Welsh/Scots, 13% Irish, and 1% Cameroon/Southern Africa.
Makes me wonder a bit about what's unique about certain regions that the results change that much (I will note that a paternal aunt of mine had, last year before the update, trace amounts of Cameroon/Southern Africa, South Asia, and Middle Eastern DNA).
Interesting that Native American DNA didn't show up despite photographic as well as genealogical evidence (unless that was the possible African ancestor passing as such, which wouldn't be the first time). I know things can, after a couple of generations, disappear from the DNA record while others are preserved much longer.
I think I'd rather do something more intensive next time, maybe the NatGeo one, or something that utilizes blood instead of saliva so I could get a better medical data set. Or maybe I could just ask a Mormon for genealogical details? 
Je suis méchant.
