Breast Pump options?

My insurance will cover the Madela pump in style advanced breast pump starter kit at no charge or the Madela tote or backpack for an upgrade fee of $100. (This one includes the backpack, extra bottles, cooler, and battery pack) Any advice on these pumps? Is buying the upgrade worth it? Im planning on just pumping at home and not returning to work so I'm not sure if I need all the extras. Thanks.
