I'm going to agree with elieandbump. I've got the babyland Chinese ones and they work far better for me than the more expensive brands. Reason is because I can just chuck them in the washing machine with other things, and they dry quickly too. They don't absorb as much as some of the more $ ones, but I've ordered some bamboo off cut boosters from 'bamboo fabric store' (google it) to put in the pocket of the nappy. These offcuts are only 75c each. So, one babyland nappy is between $5-$10 and an additional off cut is 75c. Very cheap.
I also have itti bitti and baby beehinds which are between $25-$35 each, but it's far too time consuming and too much work right now. Yes, they does absorb more though, but they're mire work that I can't find time for. I have these ones as they're left over from my trialling phase.
