I’ve been looking at having a mitochondrial or Y-line DNA sequencing done for genealogy purposes. There seem to be quite a few labs out there but the price for a comprehensive analysis is a bit steep for me (US$250-$400). I’m sure there’s a university somewhere that’ll do it for much less money.
Try ancestry.com The prices seem to be a little better. The wife and I are considering it...we are big time into genealogy.
Also, if you think you may eventually be wanting to go as high as a 37 marker test, it's cheaper to do it initially than upgrading later. I've learned some of these things the more expensive way!
