If the investment is too much right now, why don't you consider renting a pump? The Med. Symphony and Lactina are both hospital-grade pumps that work great and if you have insurance they will often reimburse a portion of your rental expense. The Lactina usually rents for a bit less than the Symphony, but if you choose the Symphony, you'll probably want to go with the Symphony Plus because it has a built-in battery pack. That way you can plug it in at home to charge overnight and then won't have to worry about having a place to plug it in when you get to work. I work at a lactation support center and my boss recently had me try out all the pumps so that I could speak knowledgeably about then to our clients. I def. felt more pampered by the Symphony, but either would certainly get the job done. Are you planning on having more children? A PIS would probably be worth the investment if you are and unless you need to use the pump to build your milk supply (like if you're not able to nurse b/c of dc's hospitalization, etc.), the PISA probably wouldn't be necessary.
