I have several from Babykins, Fetware, Baby-Pants, LL Medico, and others.
I have flannel, birdseye, and gauze. In Pull on, Contour and prefold.
I always get night time for the thickness, and have some boosters as well for extra absorbency. Probably just a little paranoid about leaking...
The bottom line (since they can get expensive) is try some that sound good and look good to you and then start to refine what you want and the suppliers you like best.
Remember, if you are going to get birdseye diapers you will need some sturdy pins and maybe go with hiback plastic pants for better coverage (sometimes I go a size higher on plastic pants to get the coverage I like).
Have fun, I hope this is of some help.
