I do not know the best. But try www.sorenson.org. They are doing free DNA tests. I do know they will not send you a result. You have to get it on-line. That way if you do not like the results or methods they use you can go with the pay sites. It does appear that you can compare results from other DNA services with their results. At present, I am waiting for my results from Sorenson. They have not processed it yet. At present, I am also awaiting results the pay DNA service from www.familytreedna.com under the Weaver surname group.
