I had a Medela double electric pump last time and this time opting to leave that one in the loft and have just got a single manual one. It depends how much you intend to pump and what for really. Lots of people find they actually get a better result with a manual. But if you want to exclusively pump or fill up the freezer with milk, it's less practical.
