I fail to see how keeping dirty nappies in a lidded bin and then putting them in a washing machine (which is entirely sealed) is in anyway unhygienic and a risk to health? Methinks some people look for any excuse to justify sending hundreds of nappies to landfill....
I used cloth nappies when DS was 2 months old, until we switched he leaked in every disposable brand we tried - and when we went to cloth we found we were saving so much washing on his clothes that it was no extra work at all.
We had about 20 nappies and washed them every other day. I also used reusable wipes and put them in the same wash (and they don't need dried before use) and so saved many pennies that way.
I never tumble dried them (I have a tumble drier but hardly ever use it due to the cost of electricity) but hung them outside in nice weather or put them on clothes horses to dry indoors. I used bumgenius v3, which were microfibre lined (really soft on babies bottom) and dried really quickly (certainly overnight on a clothes horse whether the heating was on or not).
To me, it was no hassle at all and as I'll be using them again for my current bean, it's so much more cost effective.
Also, our landfill bin is only a half bin (our council is big on recycling) and is collected every 2 weeks, so we don't have room in our bin for disposables (we actually switched to flushable cat litter as the cat litter bags were filling up our bin!).
It's your choice, and what I would say is that not every style of cloth nappy is going to suit you (or your baby). I got a subsidised nappy trial pack from our local real nappy network (basically got 6 different brand new cloth nappies and a nappy bin for 35 quid - massive saving) and this let me try them all out for a while before deciding on the brand I wanted to buy. Check your local council and see if they have any similar incentives (some places also let you hire cloth nappies for a while to see if it works for you).
Good luck with your decision :-)
