DNA Dilemma

I have spent today at a conference that was all about DNA.  There is so much information out there that it is hard to discern what test you should take and what company is the best.  After my conference today, I have come to the conclusion that one company is not really any better than the other.  It is a matter of preference.  Some companies have more a larger database than others but the tests are basically the same.  Some use a spit test and some a swab, again, a personal preference.  What you do with the DNA results is more of a challenge for some genealogists than the tests itself.
