Doula? Bradley method?

Brianne
I am trying for an unmedicated birth (FTM) and have heard great things about hiring a doula and about the Bradley method. They are both major commitments either financially or time so I want to make sure it's worth it; what are your thoughts on one verse the other or both? My husband doesn't think a doula is necessary and wants to just read about Bradley method verse classes... Advice much appreciated!
