Research all the different types of cloth diapers, as well as the covers, so you know exactly what a financial investment you're getting into -- some of them are so expensive and take so many different sizes as the baby grows, that the cost rivals the cheapest disposables.
I got my cloth diapers ("regular" sized Chinese pre-folds) and diaper pins from clothdiaper.com; and NYLON (**not** vinyl) diaper pants from tlcare.com. I started when my older son was 7 months old, and he potty-trained when he was about 2&1/2 (still uses diapers when he sleeps). When my sister's baby was born, I tried putting one of the cloth diapers on him, and it was a little hard to do -- too small and bulky if folded completely in half and turned sideways, but too big to just fold down. So, when I was pregnant again, I bought some "newborn" sized diapers.
I chose the diapers I did to save the most money, and spent probably about $125 or so for the diapers and covers that I bought (3 doz. regular diapers, 4 doz. infant diapers, and a couple packs of pants in each size). If money is not much of an issue for you, then you may want to go with some "higher-end" diapers. It takes probably 30 seconds longer to change a cloth diaper than a disposable; but if you go with an "all in one" diaper, it probably takes the same amount of time. Be advised, though, that those diapers take a long time to dry.
If I had it to do over again, I would have gotten the largest size of cloth diapers they had at the beginning, because I'm pretty sure I could have folded it in half for my newborn, and then could have just gotten one size diaper for the entire period. My younger son has started potty-training himself, and is not quite 2 (he started going in the potty, and asking to potty when he was 18 mo). I probably need to take a couple of weeks and put everything else on the back burner and just potty-train him. Probably this summer (when he can run around outside without pants on), I'll get him trained.
Anyway, there are some other cloth diapers that are adjustable and "grow with the baby" but most diapers are for one size only, so you have to buy several different sets of diapers and diaper covers.
As far as the laundry goes -- how frequently you'll have to wash depends on how many diapers you get originally and how big your washer is. With just my older son, I had to do diapers a couple of times a week -- whenever the pails got full or the stack of diapers got low. My older son was still in diapers when my younger son was born, so I did laundry every couple of days because the two diaper pails (ordinary 5-gallon buckets) were completely full. The main thing that takes time with laundry is folding it afterwards -- emptying the pails into the machine and pushing a few buttons takes just a minute or two, y'know? And you don't *have* to fold the diapers -- you can just wash them, dry them, and keep them in a laundry basket loose until you use them up.
