there was a recent thread on it...
We just use our Fuzzi Bunz as usual, and wash every couple days, (early morning for me, but, I get it done in an hour or so)
We also have used the G-diapers, which still have washable parts, but, the main part it a biodegradable/flushable insert
Also, the Gro-Baby diapers have reusable and biodegradable parts too.
