There are growing numbers of these services, most in business just a few years or less. I plan to participate in one of them, but haven't decided which: when I researched a few of them online a while back, I found a lot of negative comment, e.g., this about
GeneBase.
Complaints ranged from service (many months to results and no customer service replies) to invalid results that sound like contamination. I've seen similar complaints about other commercial services.
OTOH, I've heard good things about National Geograpic's service and that at ancestry.com. I believe the ancestry.com service allows you to register your genetic results linked to a family name, allowing (or not) contact between long lost relatives--definitely an option worth some "careful what you wish for" reflection.
NB: Wouldn't a group of siblings get the most bang for the buck by having one male sibling get the most complete results offered, rather than two siblings getting the respective tests offered each sex?
