Nursing Bras!

Hi moms I plan on breastfeeding & I'm debating on getting a nursing bra but I have a few questions. 
1. Is it a good investment? Or is it a waste? 
2. What brand did you get/ where did you get yours from & how much? 
3. How comfortable is it? If it's uncomfortable is it worth the easy access of breastfeeding? 
4. Do you still need nursing pads with your bra? 
Sorry for all the questions, I'm a first time mom and no one that I know has breastfed besides my sister who never got a nursing a bra.
