I did my Doula certification through childbirth international. Personally for me it was the best choice. The curriculum is very comprehensive and the support staff are very attentive. I felt like I was able to learn more in the time I did CBI than I would have in a weekend workshop.
The cost of the program is the complete cost, with no extras.

I am currently working on my certification through birtharts. I participated in a workshop in February, and am working my way through the workbook and other reading. I'm on call for a birth right now (any day now <grin>). I can't wait to dance!
The distance program works well for me, I can take my time and my instructor is available to me by email should I have a question. There is so much material to cover, many books to read, and I like to digest the information slowly. The workshop was a great way to start the program. I highly recommend it. I actually found out about birtharts here on tribe. One of the founders is the moderator of the birth ecology tribe: tribes.tribe.net/birthecology
here's a link to her website: www.maiahealingarts.com/birth-...-doula/

Good luck with your decision and happy future births!
Cheers!
