Wow, I say kudo's to anyone who wants to tackle that! I distinctly remember my mom using cloth on my brother. Watching her shake the poop into the toilet and then putting the dipe into a soaking pail beside the toilet was smelly and I was only 4!
I haven't done any research on the topic, but wanted to agree with Christy that there is a CD board on SK that other members have mentioned. I also heard it was a spendy adventure upfront.
I guess you would need to calculate your investment cost and add in the number of loads of laundry you are doing. If you are washing dipes 3 times every time and turning up your hot water heater, that is a considerable amount being added to your electric and water bills!
Good luck, I hear it's very addictive once you start!
