Medela Pump in Style Advanced Backpack with Avent bottles? - medela pump in style advanced backpack

I do a lot of research and I think I decided to buy my pump, I want to be in the first year of breastfeeding. Although a lot of money in front I think it is more convienent and less expensive than processed and rent a pump for a few months. My question is, will the Medela breast pumps is compatible with any other kind of bottle? My friend and I prefer Bottles Avent, Medela pump, but has the best reviews and I can not find the pump bottles everywhere. It is your experience with this pump?
