Try your local Family History Center (http://www.lds.org). They have free genealogy classes and the largest selection of genealogy data available. To rent a microfilm is only $3.75 for 6 weeks. You won't find a better deal and all the people are always willing to help you learn as well as find your ancestors.

They are located world wide and you can find the nearest location at:

or in your phone book (I do not believe this is a comprehensive list).
