I rented a Medela Symphony pump with my third. It's a hospital grade double pump and it ended up costing about $75/month plus a one time $50 fee for the starter kit. I can't say enough good things about it. I absolutely loved it. I really researched it and when I discovered it is the pump used at the Children's Hospital of Philadelphia I decided it had to be at least worth giving a try. I was really happy with it. It is super easy to use and traveled well. I also had the Medela Swing for short trips. Liked that too but definitely not for full-time pumping. Best of luck with whatever you decide!
