I need really good make up products to try!?

okay so i have oily skin and some problem areas that occur on my skin. ive been using only a powder just because i dont like the feeling of heavy make up and the the powder ive been using is physicians formula but i dont really like it anymore because it has sparkles. also i use a mac concealer but its kind of expensive so i was wondering if anyone could give me great foundation tips and some great cheap brands of concealer as well that work!!! :)
