Makeup!!!

Hey ladies! I need some foundation sugguestions. I have combination skin so an oil-free, mattifying foundation is a must have. I'd prefer something more lightweight than MAC, which is what I currently have. I have acne-prone skin so something good for sensitive skin is ideal, and weird colored skin so a lot of color options is a must. My price range would be from drugstore to maybe $45. Thanks for the sugguestions~
