Birthing center experiences/testimonials

I think I've finally made the decisions to birth in a birthing center. I had my first in hospital by an OB without epidural and just think a midwife is more trained in my specific birthing plan. 
Anyone else deliver in birthing center?  How was the experience?  I'm nurvous but excited at the same time. 
Unfortunately I could only find a CPM not a CNM. Hopefully all will go well. Did any of you ladies use a CPM?
