It depends on how much you consider an arm and a leg. I rented the hospital grade pump and paid $60 a month for it for 7 months and it was worth every penny. It was a dual pump and worked like a charm. It also depends on how often you are going to be pumping. My son would not latch, no matter how much everyone tried, so I had to pump for every little bit of breast-milk he got. So, I needed something really solid to help me. If you are only going to pump once a day, you can get a single pump (Medela makes a great one). Or you can pay a bit more for a dual electric pump if you intend to pump a couple times a day (the time saving will be worth it and your hand will certainly thank you for not giving it the workout that the manual pump does!). I definitely liked the Medela line, as I had a manual single pump, very helpful for when our power went out in the winter.
Not sure if that helped, but if you want more info, PM me.
