I used hydrotherapy for most of all of my labors. I was not able to have a waterbirth, though, as I chose hospital births and it is against their policies (phoey, I know).
I have attended a few women in waterbirths, though, and it is a beautiful event. You can buy Noa Was Born (a beautiful waterbirth DVD) from Wise Woman Childbirth online for about $10.
Good for you though and I can't wait to hear your beautiful waterbirth story!
