I started cloth diapering my daughter exclusively when she was 10 mos. old too. It was the best decision I've ever made. We use bum genius, happy heiny's, prefolds and covers, and a few other brands that we've picked up along the way. I love the bum genius for dryness, but I find that the fit isn't as good as happy heiny's one-size. I would suggest to you before you go all in on one type of diaper, to try out a few different kinds. We generally use prefolds the most and they are by far the cheapest way. So don't rule those out.
As far as rashes go. There are a lot of reasons for rashes occurring and they don't necessarily have to do with the cloth diaper itself. It can be the detergent, food allergies (My daughter started having awful rashes about a month after we started cloth diapers and it ended up being because of food which we had just started around the same time), or (and I hate to say this because it certainly doesn't explain all rashes) not changing the diapers enough. It's true, with cloth diapers, you may find that you're changing more diapers, but it's only because we're trained with disposables that even if there's a little pee in it, we let it go until "it's full". Studies actually show that cloth diapered babies have 70% less rashes, but there are obvious exceptions.
If you have any questions, I'd be happy to answer them! You can also check out diaperpin.com. They have reviews of all kinds of cloth diapers and lots of cloth diapering information.
