Electric versus manual pump?

Marisa
I exclusively pumped with my older son (he was a preemie and we started that way and just kept it up). But this time around I would like to mostly just nurse. However I would like to pump occasionally. Is a manual pump easier? Worth it? I've read it works better and faster for occasional pumping. I have a 3 year old so being tied to wires isn't always going to work either. I have an electric pump, just wondering if it would be worth it to get a manual one?
