Breast pump

So I can't get an actual electric breastpump through my insurance until my baby is born, but I've considered getting just a manual pump to keep in my diaper bag until I can get a electric one. What's everyone's opinions on manual vs electric? And whether you should have both? I've heard it's good to pump while in the hospital to get your supply in quicker.
