Depends how and what for... i pump 3 times a day at work and have limited time. I have an Ameda double Lactaline electric and wouldn't be without it - you can control the speed and suction so you can trigger more letdowns. A double is essential if you're going to be pumping at work regularly I think. The guarantee on the motor is a year, unlike Medela which is 3 months (or was on my medela mini double electric, which conked out just after 3 months). The swing is meant to be very good though, just not adouble.
