I know there are a million posts about this, but I'm starting yet another one because I really can't decide. If you've used one or both, let me know what you think!

I had a Medela PISA with DD1, and it did just fine. I assumed I'd get the same thing for DD2 (due in a month), but there are tons more options this time around. (The Freemie is one, too, but I think I've decided against that.) I've narrowed it down to:

Medela PISA
-Pro: I can use all the same parts and bottles. (This is big...seems like a pain to have two sets of parts. I'd like to keep one pump at work and one at home if possible.)

Spectra S2:
-Pro: I've heard great things. IS IT WORTH IT?!
-Con: Different parts. See above.
-Con: Bigger than the PISA (Is this true?)

HELP ME! Please?
