If I had no other option I would want an Ameda with the hygenikit (Purely Yours?). If I remember correctly the hygenikit prevents the milk from backing into the motor. I think this is pretty much the same technology they use on hospital grade, multi-user pumps. The difference is the durability of the motor and the fact that the multi-user motors can be sanitized and the personal use motor can't be. (Both of which increase the cost of the pump, BTW.)
I personally have spilled milk into the insulated compartment of my Medela PIS, and it leaked into the motor below, so the Ameda hygenikit is no guarantee that there are no pathogens in a used motor.
My next requirement would be a pump that hadn't been used in awhile, to try and ensure that any pathogens had died. But how long is long enough? Especially since (as I mentioned earlier) the yeast and the mold can probably survive for awhile; and even if it goes dormant moisture can reactivate the yeast, and I would imagine the mold as well.
And really, who would want old/inactive mold backing into their baby's milk?
I think you can take the PIS/A "diaphragm" off (although that's not recommended) and you could see any mold there but that doesn't rule out mold in the motor.
Assuming I was willing to take the risk of yeast or mold , I would then run the unit and see how many pumps it was putting out per minute. If I recall correctly a good double pump will cycle 54 to 56 times per minute when new. When I learned this I counted the one I got from my sister --several months into my using it-- I think it was operating at about 36 per minute. The Medela PISA I bought when I realized how inefficient my sister's was dropped from 54 or 56 to about 46. So I took a calculated risk and re-usued it for DD2.
Keep in mind that even if it is pumping between 45 and 55 or so cycles per minute you have no way of know how strong the suction is. I don't know that there is a direct relationship between the number of suctions and their strength. I think there is a tool for measuring suction on hospital grade pump motors but I don't know that they can be used on personal use ones.
And, as you know, even a good double electric pump cannot produce milk as efficiently as a baby. A deteriorated motor can easily undermine a mom's supply so using an older one might be a false economy/savings, even without the question of pathogens. I spent a small fortune on galactagogues. Probably enough to finance an Ameda PIS.
Finally even if the cycles and pumps seem adequate when you get it the likelihood is that the motor will continue to deteriorate and you will need to buy one anyway. If there is any possible way to buy one up front you should do it then to improve your "baseline" supply which is established in the early weeks (through 5 or 6 weeks if I remember correctly). Especially if you aren't getting it for free since the $25 or $50 you are spending could be put towards the new one.
