I would go for the Y-46 test if ordering through Ancestry.com. If ordering through myFTDNA, I would probably stick with the Y-67 panel, but the Y-111 panel is a real possibility if you can afford it. The Ancestry autosomal DNA test is cheaper and provides more results down both maternal and paternal lines, but you've really got to have some patience in interpreting the results and matches. Once you get the hang of it though, I think you'll really appreciate what it offers. I'd stay away from the mtDNA tests unless you've got a real reason to view those results.
