My midwife rents hers out, but I think she only has one and most of her clients want a waterbirth. I would ask your midwife if you have one. If not if you just call one of them, I'm sure they can point you in the right direction. My midwife's name is Gerri Ryan and here is her site if you need to get in contact with her. Post again if that doesn't get you anywhere and I will help you find one!
