To Doula or Not To Doula?

Hi ladies!!
  
FTM mom here. I'm considering all options of labor and birth, I've decided I want my husband with me during labor, I don't have a mom and my MIL won't be in the labor room.
  
I have heard many benefits of having a Doula, but am concerned that it will take the spotlight off of hubby/make him feel useless or overlooked. He wants very much to be involved in labor and the whole process!
  
I'm wondering from moms who have had a Doula (or maybe there are some Doula's on here) what were the pros and cons for you?
What did you like and didn't you like? Did hubby feel included still? 
  
Cost is not a problem, I have money put aside incase we do decide to have one. I'm more interested in the emotional pros and cons.
Thank you so much in advance!!!
