Foundation Recommendations?

I recently started doing full face make up but I am having trouble with foundation. I have lots of acne marks and I can't seem to find a good foundation to cover them without making me look cakey as well. I currently use the NYX foundation but it comes off just by me sweating and I feel like I don't get the coverage I want without making me look cakey. I've heard of the Fenty foundation and Estee Lauder double wear but I can't afford it :( anyone know any good drugstore foundation?
