Lancome, expensive but they make amazing primers or try Estee Lauder's Double Wear Light Foundation. It goes on very smoothly, and will last you a guaranteed 15hours, even if you don't use primer! Also, the formula is very light and great for people with oily, acne prone skin.
I absolutely love Clarins Instant Smooth Perfecting Touch. It doesn't bead up or flake upon application. It has a matte finish. A little goes a long way. Can even be worn alone, it does a lot to really smooth over enlarged pores/wrinkles. Makeup application after applying it is really nice.
