On the old forum, there was a thread that included suggestions for web sites for buying the PIS. Medela prevents many web sites from listing prices (which often means that they are cheaper than the average price at big retailers). From that thread, I found hackleyhme.com, which has the PIS original for $190 and the Advanced for $220. Does anyone know of a better deal? I'm a little wary of buying one used on eBay, but I'm also a grad student on a budget.
