We love cloth. Ive used them since my DD was born. mostly uk brands so i cant help you there, but i have used motherease (wraps are awesome) and fuzzy bunz too.
theres various types
2 part nappies which are terry/cloth inner(usually shaped now but some use terry squares still), with an outer waterproof wrap (you can get lots of cute ones), you use the wrap more than once, but the terry bit goes in the wash. the down side to this is that the wetness of a terry is on the baby's skin, but you can use fleece liners to help that. these come in 2-3 sizes, you usually use size 1 from newborn to 9 months and size 2 upwards til potty training. (i've mostly used these type)
pocket nappies which also have two parts, the outer bit with the pocket that you stuff with a soaker... adding more absorbancy is easy as you just put extra boosters/soakers in. soakers come in various absorbant fabrics including microfibre, hemp, bamboo, terry etc.
the inside of the 'pocket' has fleece which pee goes right through and keeps the baby dryer. The whole thing goes into the wash once its soiled/wet. you can get birth to potty sizes for these now, which means only one set of nappies! some come in different sizes though, depends on the brand.
all in ones which are just like disposible except washable, just one part that you take on and off, these seem easy but it means you can't adjust the absorbancy as easily as with the other two.
now you can get part disposible/part washable and i'm sure someone will be along shortly to explain.
When it comes to washing we just chuck them in a dry bin until we have enough to wash, then wash on a 60degrees(thats uk though!) with no fabric conditioner (this puts oil in them and makes them less absorbant)
you'll need about 15-20 for full time use... to be honest the more the merrier... you can never have too many!! if you're doing cloth you may as well go cloth wipes as well as they all go in the same wash and its no more hassle really.
by going cloth its better for your baby(less chemicals on the skin), and miles better when it comes to landfill sites... it takes hundreds of years for disposibles to break down. it also takes alot of trees and oil to make disposible nappies before they even get on your baby.
