I have researched this one a bit. 23 and me is pretty easy and convenient but it is incomplete and can be a little misleading. I suggest you get their test and then run your data through promethease for better insights. I'd be happy to help anyone that needs it.

You don't need to bother with 23andme and their prices (several hundred bucks if I recall). If you are willing to share the data (and let's face it that's gonna happen anyway) you can get a free sequencing from the Personal Genome Project.
