Best bottle for breastfeeding

I'm going to breastfeed but I'm thinking about pumping some bottles for if we decide to go out. What bottles would you reccommend that won't cause nipple confusion? I used Avent with my daughter but we didn't give her a bottle until I stopped breastfeeding and started formula. I'm currently 14 weeks 4 days with baby #2 but I'm just looking for suggestions. I'm not a fan of Dr Brown but any other ideas.. Fire away! :)
