Natural Non Comedogenic Foundation for Combination Skin?

I would like to start experimenting with make-up a little more and want to find a natural foundation that won't clog my pores. Something affordable or at least not outrageously priced that I can buy in a store, not online, is what I'd like. My skin is combination. I get blackheads around my nose sometimes and pimples in the crook of my chin below my lower lip. My forehead gets oily fast, but the rest of skin tends to be dry. I really what something that won't clog my pores. If anyone has used a good product like this and can give me a review of what they thought I'd really appreciate it! It has to be natural.
