Breast pumps!! Recommendations please

So I am 20 weeks with baby number 2. I am planning on exclusively breastfeeding at least 6 months if not longer, fingers crossed. I will get a free Medela pump from WIC but I won't be able to get it until baby is 2 weeks old and I know from baby number 1 that I will need something until then. Can anyone recommend a cheaper pump that will be good until I get the other one? I'm not wanting to spend more than $100 since I will be getting the nice Medela one for free. Thanks!!
