The Imagine brand is only available through Nicki's Diapers. The price is really great and the quality is good. Even when it was not (I had a snap break after only one use), they gave great customer service and sent a replacement.
I only wish they actually fit my baby. I think the minimum waist size they will work on is 14 inches, and my baby is under that. I tried snap and velcro and even the tightest setting on the velcro was not tight enough! That's the main reason I ended up using Best Bottom diapers, but if you have a baby with normal proportions, I think these covers are nice. I hope to try them again when my baby is a little bigger!
