Cloth diapers on baby registry

JG
I'm a first time mom and planning on cloth diapering. I'd like to include diapers on our registry to help defray some of the cost, and most of the advice I've been given has been to try out different brands and styles to see what works for us.
If you're a fellow first timer, how have you approached your registry? What styles did you register for, and how many of each?
