Best breast pump for working mom with a toddler?

I'm looking for recommendations on breast pumps. I work part time and I will have a 2 year old. I have insurance but they offer a variety of pumps and I'm not sure which one to get. With my first I had the medela in style advanced and it did it's job. It was a little loud and needed to be plugged into a wall at all times, but it lasted the year I breastfed. This time around with a toddler I would really love a pump with rechargeable batteries so I don't have to sit connected to an outlet the whole time. I loved the letdown button on my medela as well so that would be a plus. Lastly I would love a pump with adjustable suction. I plan on EBF for one year again. Preferably a pump that would be under like $300 but like I said my insurance does offer free pumps and discounted pumps so your recommendation may qualify. Thank you for any feedback!
