I loved my cloth nappies and found them brilliant when i got used to them, I only started using them when Jack was about 8/9 months old, so newborn wise, Kina Beanie and Helen are prob your best bets
Loads of info here
Cloth Nappies-I need an idiots guide and other threads there
As for cost, it really depends on what you go for and if you develop an obsession!!!
Any questions i'll try and help you as best i can
