Electric breast pump

Ask ko lang po ano maganda brand ng electric breast pump. I'm on my 5th month now and based on my first pregnancy, sadly 3rd day na po ata ako ngka-milk so yun first born ko nasanay sa formula milk, though he grew up healthy nman po and no issue, I just don't want to deprive my second child of my milk, so as early as now I want to be prepared..I want to buy before my due date. Thanks po ?
