Spend the $ on a medela. Totally worth it. Also you may be able to get your doctor to write a script for it and then your insurance might cover it. Also going through a medical supply place you can get a hospital grade pump which is way better than one you buy at a retail store.
Medela's are good pumps. I used an electric only because I went back to work and it was faster. I used the manual when I was at home. As long as you are getting your milk that is all that matters.
I had a medela and I loved it I liked the maunal on better though the electric one hurt me.
