Hi Dexter & Hiatt, welcome to the forum
I have been researching my ancestry through free sources (not worked out where the tight gene came from yet!), and can recommend the mormon church (church of jesus christ and latterday saints) as an excellent resource.
Part of their belief system is that if someone converts then their ancestors are converted too, even if they died centuries ago, making genealogy an important part of their church.
Their network of family history centres throughout the country hold copies of all the available censuses and most of the parish records, they are welcoming to people who are not of their faith and will make all the info they have available to you if you ask nicely!
I have used their family history centre in plymouth several times, and nobody attempted to convert me, they even ordered in a copy of an census that they didnt hold in that branch to help me with my research.
some of the info that they hold is available free online too at http://www.familysearch.org/eng/default.asp
you can also use that site to find your local family history centre which will hold microfiches of censuses and other records that they have not put online.
hope this helps
