Doula in training?

This is my 3rd child and I'm looking to have an all natural hospital birth this time around. I am looking into hiring a doula but see that they can be a bit pricey. I have seen doulas in training are a fraction of the cost and was wondering if anyone has used a doula in training, and what was their experience? Thank you.
