I have combination skin, it has been more dry since I am pregnant so I have had to step out of my normal matte only make up! Typically I am pretty oily in my T zone.  I really like Sonja Kashuk foundations around $13 at Target.  They don’t have a huge color selection, I mix two colors to achieve my color.  It goes on well and works with my oily and dry skin.  I use a primer also.  The wet’n’wild foundation is amazing, especially at $6! Love the coverage and finish.  The L’Oréal  infallible matte ($11) is really good also, but kinda drying on my cheeks.  My skin is normally not this drying so probably revert back once I’m not prego! The L’Oréal lumi ($10) is really nice also, but where I get oily I don’t use it on because it does tends to break up, even with a primer and setting powder.
