Breast Pumps? Brands? Manual vs Automatic?

Hi all I'm a ftm and been thinking more and More about breast pumps.. I'm currently 28 weeks pregnant so I feel like I should start looking. What brand have you used and had success with and did you prefer manual or automatic? I'm totally lost when it comes to this and I'm worried about being sore etc. My pump is not covered through insurance so it will be out of pocket but I'm planning on more children in the future so I don't mind making an investment purchase if it's a great product I can use again. I would greatly appreciate your advice!
