In my researching I found a few more CD sites that I found helpful:
Jillians Drawers: http://jilliansdrawers.com/
They have trial packages available for $10 and I found their product reviews very helpful and have more pics for most their products than Kelly's Closet. However, Kelly's Closet seems to have more cloth diapers.
I also found Mommy's Milk Boutique: http://www.momsmilkboutique.com/
They also offer trial packages & have a great variety of products in addition to CDs. Mommy's Milk Boutique also offers free shipping in the United States!
I wish I had discovered these sites earlier. I could have purchased a trial pack to figure out what diapers I like best before purchasing a greater number of them. Like I did with the GroBaby diapers. I have also found Kim with the Dirty Diaper Laundry: http://dirtydiaperlaundry.com. She has given many helpful cloth diaper reviews on a variety of cloth diapers.
