What is some really good foundation that I can buy at a drug store?

I use to shop at sephora for foundation but it was just unnecessarily expensive. Does anyone know any good brands that will make my skin look kind of like porcelain that I could find in like, a walmart or drug store? Every brand I've picked out myself makes it obvious that im wearing makeup and it just looks trashy looking. I don't care if it's powder or liquid, neither of them bother me. Thanks a lot(:
