I have a Medela Pump In Style (I think that's the name) - it's fantastic. But I started out with a rental through the ABA of a hospital grade medela - it was fantastic (my PIS isn't far off though). The best investment I made in terms of pumping was a hands free bra that holds the funnels in place - I can use the computer while I pump! you don't even need to buy one - I hear that with a good fitting sports bra, if you cut slits, you can make your own hands free bra.
