A friend of mine passed me her messenger-style Medela PIS. I did not end up using it, and I would like to donate it to someone who could. It is, as far as I know, in working condition and could have been purchased as early as 2005 (not sure if she used it for both children or just the younger). It comes with a plug adapter and several Medela quick-steam microwave bags.
You would need to purchase new accessories - tubing, flanges, valves, etc. I would be donating this with the understanding that you realize that the Medela PIS is a one-user product and you assume any responsibility.
I am in Arlington (and cross-posting with the DC board).
