Ultralight lessons?

Okay guys, I need some opinions. Due to financial reasons (house and vechicle payments, wife in school, and my overpaid government position ::)) it's gonna be a while before I can swing getting my private ticket. I started thinking about maybe trying ultralights. I figure it's gotta be cheaper and easier to start out on. Can anyone give me a idea about the cost and requirements? I live in the Southeast United States (I figure the U.K. will have different figures). Thanks
