Dr. Brown's Natural Electric Breast Pump

I am hoping to find out about some breast pumps. If you have any recommendations, they would be appreciated. I am using an Ameda Purely Yours right now, and love it, but am interested in a single electric pump. There doesn't seem to be much of a selection. I want to be free to move around, but still have the control over suction and cycles. Thanks!
