The only thing I'd change about my Medela Pump in Style would be the bag. I'd get the Metro bag instead of the backpack. Workhorse for me for a year and I could probably fire it back up right now. You can use less expensive bottles (esp. if baby prefers something that doesn't fit) for pumping. Hint: you may be able to get it covered by insurance as a medical device and/or you may be able to get it after baby is born if you add it to your registry and then leave it "unfulfilled" BRU gave me a 10% coupon that I used to get it after DD was born. I used the battery pack, but you could use the car adapter if you need to/have a long commute/might use it on the way home after a nice dinner.
Whatever you get, I agree not to go with Evenflo or Playtex. You might already know, but I suggest you get measured for the right sized horn things if your output is wonky. Any of the 3 mentioned should be able to swap out horns to get the best fit. Made a HUGE difference in my output.
