I assume you're in the states? If insurance will cover a new pump, I would get a new one. Reason for that is that if the old one stops working within the 3-6mo post partum period that they will cover a pump, you don't want to be left paying out of pocket. I donated my old one to a local church (who found someone who couldn't afford one and needed it) and got a new one even though I'm not planning to use it. I figured if the worst happens and I have to find a job to scrape by before DS2 is ready to stop drinking milk during the day, I'll have a good pump, and if I don't use it, someone in need will get a new pump in a couple years' time.
