i'm a father but i bought breastpump for my wife.. its all depends on your budget.. but my advice would be electric and double pump especially for a working mom.
i bought it from ebay around 3 years ago and the price is almost 1k cheaper than buying here. Medela Freestyle. If not mistaken you can also get a cheap price from http://www.mybreastpumpshop.com/ where the owner get the stock directly from US.
Breastpump recommend
