If you use cloth diapers, what made you decide to use them?

binoxi asked:

I've been thinking about using cloth diapers and am having a hard time deciding which is more beneficial for me. I would like to know what made other people decide to use them!

environment?
cost?
upbringing?
I want to use cloth because of the money it will save me! We don't make a lot right now and cloth may be better in the long run!
