Anyone still thinking about joining in the fascination of dna projects but put off by the cost, now is an excellent time to jump in.
Family Tree DNA are offering a great discount on their Y-DNA37 test, throwing in an mtDNA test for less than the usual price of just the Y-DNA37 and significantly less than the usual price for this combined test.
37 markers is a good entry level for genealogical purposes, and can always be upgraded to 67 at a later stage if interesting matches ensue.
Find your surname of choice, and join the relevant project.
The ones I have an interest in are all on DNA Surnames, but a search at either the World Families Network pages, or Family Tree DNA will give you more options.
