I'm not sure about that particular brand... I had a second-hand Madela pump in style that worked well, but I had better results with an Aveeno manual pump. The manual one came with a sort of "comfort petal" thing that went into the cup part, but it worked better without. Lol.
I would recommend finding a cheap manual one until you decide if you will actually need one.
I actually pumped quite a bit when I was home with my baby. I was an over producer with a forceful letdown, so I had to pump an ounce or two before trying to put my DD to breast. If I didn't, the stream would shoot out so hard that my baby would choke on it. (Seriously, we measured once and I managed to shoot over 6 feet! Lol.)
Plus, I am shy about nursing in public. Next baby, I hope to be more confident... But for my first, I just couldn't do it if I had another option. I was *that* mom who would hide out in changing rooms or run all the way back to my car if my DD got hungry while in public. So, if I knew I would be out long enough that my DD would need to eat, I would pump out a bottle for her. :) I am a huge advocate for the right to nurse in public, but I also strongly believe that each mother should do what makes her most comfortable.
I also stockpiled milk in my freezer. After every nursing session, I pumped out the 'leftovers' and froze them. (Which, I'm sure, contributed to my over-producing... lol.) This worked out great, because I DID wind up going to work part-time after my DD was about 3-4 months old. When I did, my supply dropped BAD. If I hadn't stockpiled, I would have had to supplement with formula. As it was, I managed to use about 3 weeks worth of frozen milk before I leveled back out... Then I was pumping bottles for Daddy to give her while I was at work.
Plus, it's nice to be able to pump out a bottle and let Daddy have some bonding time during feeding as well. :)
ETA: also, spicy food never bothered my DD either.... But DAIRY did! For about 6 months, I had to reallllllly limit my dairy intake. She did grow out of it though. :)
