Re: Should I hold on to my old pump?
The pump is unlikely to last if you have another baby. But it's also not guaranteed to fail! An old PISA might or might not make it as a full-time work pump, but it would definitely make a good back-up pump for home use. And while I don't know if you can totally refurbish a PISA, changing the diaphragms and tubing might bring it back up to like-new condition.
If you decide to bid your old PISA goodbye, at least give your local La Leche League a call, and ask if they would like it. There are a lot of moms out there who need electric pumps and can't afford them, and though the official LLL position is that pumps like the PISA are "single user" devices, I have seen pumps passed from LLL mom to LLL mom on an unofficial basis.
