I have both my girls in cloth. I'm using Baby Beehind fitted nappies. Emily was in AIO's until last week, when the fitted nappies started fitting her better.
I have about 25, and have just ordered another 10, and I wash every 2nd day. I have a variety of covers. PUL, wool & fleece.
You will definitely save $$$ by using MCN. Like Ashley said, Baby Beehinds have a 16 week layby which is handy.
And like MantaRay said, Nelle started a really good thread for beginners.
