Whoever said that cheap is far from best needs to re-assess their life choices

Expensive is not a guarantee, it won't always work, even if you use it correctly.
What look you're going for? soft and feminine? Do you struggle with beard shadow?
Where you from? I'm from Europe, don't know much about US makeup but hey ho.
I'd say:
Foundation: Bourjois. I think they're really good quality and colours. Find the right shade and you're good to go.
Brushes: get them from eBay, the ones from China are incredibly good, and on auctions you can get a whole sets for like few dollars literally.
Powder: I like Rimmel stay matte, but look for transparent, loose powders.
Blusher and lips: I love elf lipsticks, they're amazing quality, colour pay off etc. Use lipstick as a blusher, blend it with your fingers. Other good lipstick brands are NYX, but some of their shades are a miss.
Gel liner: Maybelline. Cheap and brilliant.
Mascara: Covergirl lash blast.
False eyelashes: Ardell or Red cherry lashes.
Eyeshadows? I wouldn't bother. Unless you got blue eyes, I don't think they do anything for the eye, stick to gel liner to elongate your eye and add dimension.
Good luck!
